All the new MacBook Pro reviews rave about the aluminum design.

It is claimed that the remarkably sturdy hardware of the MacBook Pro was built by computer numerical control machines, which are the same machines that create essential parts of spacecraft bodies.

The result is a highly durable, sleek and lightweight design that takes far less material to make than most other laptop designs.

Even the box that holds the Macbook was made with less material so that there is not as much packaging waste.

Other new MacBook Pro reviews state that additional environmentally friendly features include that it’s arsenic, BFR, mercury and PVC free, making it not only healthy for the environment, but healthy for users too

The new body makes for a lighter notepad and at 5lbs 6oz is lighter than many ladies handbags (7lb 11oz, Daily Mail).

Some of the features that make the MacBook Pro even more user friendly than past MacBook designs are simple, yet highly innovative modifications.

The trackpad, for example, incorporates the touchpad and right and left button in one easy-to-use device.

You can do even more with the trackpad than simply swiping your fingers across the pad.

I also can’t believe how long the battery life of the new Mac is. New MacBook Pro 2011 reviews stated that the 13 inch design can last up to ten hours, while the 15 and 17 inch designs range from eight to nine hours.

This is by far the most battery life I’ve seen yet from any laptop or notebook computer.

Other features, such as better graphics and the Turbo Boost and Hyper-Threading speed applications allow the newest edition in MacBook to be even more intuitive and practical for users.

No product is infallible, and so it is with the Macbook Pros.

The 17 inch model gives you a choice of a glossy or matte finish on the display; whereas the new 15 inch is glossy only, which might prove a problem for those whose first priority is not watching movies on a $2000 laptop.

But there’s no denying that the new MacBook Pro 2011 will usher in a variety of new elements to the world of computers. With all the new features included, it is sure to be one of the most sought after laptops on the market yet.

If you think all flat panels are the same, you haven't seen the stuff I'm about to show you. Remember that Wi-Fi 1080p plasma we told you about in April? Well that's it, above, and look ma, no wires. (Okay, there's a power cable plugged into the wall — who do you think built it, Nikolai Tesla?) After the jump, I'll show you the front and back of A/V box that the wireless TV uses, and maybe clue you into the joys of LED backlighting and 120Hz motion-blur reduction. (That last term has a kind of purr to it, am I right?

According to Samsung, this is the world's first 1080p Wi-Fi plasma. That's a lot of qualifiers, but it is pretty tasty, and according to the company, the issue of getting Hollywood's permission to stream 1080p video from Blu-ray or HD DVD is being resolved, and the TVs will ship in early October. They will be at 50" and 58" sizes, and will cost $600 more than the equivalent plasmas without Wi-Fi. Note the USB jack next to the HDMI input.

LED backlighting is the wave of the future for LCDs, and not just because they are "greener" than the current CCFLs. Because they can alternately dim and brighten 60 or 70 separate clusters of LEDs underneath the LCD panel, you get deeper contrast, but without losing detail in dark scenes. The TV in the shot below is the previously announced but never-before-shown LN-T4681F, a 46" set that will list for around $3,500. (Though the screen shows that idiotic Robots movie, the best demo of the TV's shadow and explosion capability was Batman Begins.

Finally, we turn to 120Hz. As many commenters have acknowledged, there are plenty of different types of 120Hz systems, and many different claims. I think the best ones are the ones that use image processing to interpolate new frames. (And yes, there are different types of interpolation, too, but let's skip that for now.) If you look at the photo I snapped of the TV here, Samsung's $3,000 46" LN-T4671F, you can actually see that for every two frames on the right, there's only one on the left. The camera don't lie, and believe me, it looked good in person too.

Samsung NC10

Screen Size: 10.2”
Battery Life: 5 Hours
Operating System: Windows XP
Weight: 2.8lbs

Samsungs entry to the market is the exact opposite of some of the niche systems we've already run through, sharing more in common with the EEE PC line - it's powerful, small and focuses on doing simple tasks as well as possible. Thanks to this focus on simplicity, the NC10 remains an excellent contender despite doing nothing 'special'.

The Samsungs design is piratical and uses a 10" screen. From the outside it looks like the epitome of a standard small laptop. It's not stylish but nor is it over-the-top, and it could easily be mistaken for just about every other non-descript small laptop on the market.

One of the ways the NC10 does differ from other models is that there are no options in terms of changing any of the specifications. There's no Linux version, no different CPU speeds, no option for a solid state drive. It offers a standard Intel Atom N270 configuration running at 1.6 GHz, 1GB of ram and a 160GB hard drive.

Control on the system is hit and miss. The 10" size has made the keyboard large and easy to use even if it's not the best on offer. However, the touchpad is awkwardly placed and oddly unresponsive. Worse still, Samsung have taken the rather odd design decision to make a 'widescreen' style touchpad which makes vertical scrolling a somewhat ardous task.

The systems Matte display runs at the 1024x600 and looks appealing and crisp, although it would be hard to differentiate between the NC10 and offerings from ASUS or Dell in terms of pure screen quality. Sound offers a similar 'adequate' quality without providing any real power. The integrated 1.3MP webcam however does stand out as one of the best in the world of small laptops and combined with a decent microphone it's a great system for talking to friends over the net.

Battery life is one of the few absolute standouts of the NC10, featuring a 6-cell standard battery that even beats out contenders like the EEE PC. Depending on the tasks and the brightness of the screen, the system can last for around 5 hours. The NC10 is also priced perfectly; at around $450-$500 - slightly cheaper than many of its direct competition.

Sony VAIO VGN-P588E Lifestyle PC

Screen Size: 8”
Battery Life: 2.5 Hours
Operating System: Windows Vista Home Premium
Weight: 1.4lbs
Wow, that's a bit of a mouthful, isn't it? It's a rather pretentious name for what is essentially just another small laptop, but then the Vaio range has always been one for style and design following just behind apple in desirability ratings. It’s popular amongst people with the disposable income to afford to pay for the brand as well as the components.

And there's no denying that the P5's design is excellent. It's stylish without being loud. It’s thin and elegant. It looks like no other small laptop on the market, so if you're after some visual originality, the P5 has to be right up there with anything Apple can offer. It comes with a price tag to match the design however, weighing in it over a thousand dollars.

The Sony model opts for an 8 inch widescreen display, offering a resolution of 1,600 x 768, slightly different from the usual notebook standard. In fact, it's one of the best resolutions around for a system of its size and because the screen is so wide, there’s far less chance you'll have to worry about scrolling.
Sony's small laptop is also unusual in its decision to use a pointing stick rather than a touch pad to save space. Some people really dislike pointing sticks and find them slow and difficult to use, while others actually prefer them to a touchpad.. The keyboard is adequate and doesn't have any major faults, though as one of the smaller laptops in this list the lack of space does making typing quite a challenge for those with big hands.

One rather confusing design decision was the move to Windows Vista as opposed to more lightweight systems like Linux or XP. The P5 comes equipped with 2GB of ram, but where better operating systems would fly Vista feels slow and cumbersome. It's important to weigh in the resource load of the operating system when directly comparing system technical specifications. Of course, the eye catching design of Vista fits very well into the P5’s own visual attractiveness.

Extra features are what make the P5 stand out amongst cheaper competitors. It has .11n wireless which is faster than standard, GPS, Bluetooth and even integrated mobile broadband. This makes it highly connectable which is a massive bonus for a portable device. Combine this with its weight and fact it's less than inch thick and it's one of the best devices out there in terms of pure portability.

The battery life of the laptop is the only crutch on portability, offering just over 2 hours under heavy use. You could probably get more out of the system by swapping to a less battery draining operating system. Sony also offers a larger capacity battery that nearly doubles the life of the system, but it does stick out of the P5 and it costs another $100 on top of the already heavy price tag.

HP Mini 1000

Screen Size: 8.9” / 10.2”
Battery Life: 3 hours
Operating System: Windows XP / Linux (Ubuntu)
Weight: 2.5lbs

HP’s last small laptop offering was the 2133. It was an interesting attempt at the market with an excellent control interface and keyboard. Unfortunately, use of a budget processor and a high price range meant the system couldn’t quite cut it amongst its competitors at the time. The Mini 1000 is HP’s consumer answer to the 2133, lifting the excellent keyboard straight from the business model while upgrading the CPU to the much more powerful Intel Atom.

The Mini 1000 runs on Windows XP, uses a 1.6 Ghz Intel Atom processor and comes with 1Gb or 2Gb memory options as standard. Nine or ten inch screens are available depending on preference and price range, and everything is powered by a standard 3-cell battery. The 'Mini' version of the range runsWindows XP but the 'Mi' runs Ubuntu Linux complete with proprietary HP media software. Hard drive options include a spinning 60GB drive or an 8/16GB solid state solution.

Like most HP machines, the 1000 stands out in the small laptop market for both its stylish design and light weight form factor. HP thankfully swapped out the metal chassis from the 2133 with plastic - it looks cheaper, sure, but you also save money and in weight in the swap. The laptop remains attractive once opened with an excellent use of the limited space on offer.

The amazing thing about the Mini 1000 and the thing that many people considering purchasing a small notebook should consider is the size of the keyboard. HP claim the keyboard on the 1000 is 92% of the size of a regular laptop keyboard. That's quite an achievement, and in terms of typing if nothing else, the 1000 is the best in the market. This makes the HP product perfect for people who have had a bad experience with key mashing or pain when using other small laptop keyboards.

The 10 inch display model offers the standard 1024x600 resolution seen in many small laptops. As with much of HP's laptop range, the screen is covered in gloss which makes the display look fantastic - inside. Outside on a sunny day you'll be constantly trying to adjust the screen to avoid reflection, a shame considering it does limit the portability of the device somewhat.

The only thing that lets the 1000 down slightly is the rather confusing decisions HP has made with the systems ports. The 1000 has 2 USB ports and only one port for audio. There's actually plenty of room for the extra ports but HP has decided to use the space for a proprietary system called 'Mini mobile drive'. Mini mobile drive is nothing more than a high capacity memory stick that you can only buy from HP, and we can't see any reason why most small laptop users would ever find a use for one.

The Mini 1000 retails from $500 depending on your options with the 'designer' Vivienne Tam edition selling for a ridiculously high $700+. We recommend grabbing the Windows XP 'Mini' range over the 'Mi' as the extra money you have to spend on Windows gives you so much more software options. An extend battery might also be on the cards for some users as the 1000 uses a 3-cell system that will only last around 2.5 hours under heavy use.

Fujitsu Siemens turned things around with the biggest laptop in the world presented at this year’s CeBIT show in Hannover, Germany. A laptop can only be called a laptop if it fits on my lap. If, instead, the whole of my body can fit on its keyboard, and the screen is big enough to kill me if it suddenly drops, it is not a laptop anymore- how about a cracktop?

First Generation (1941-1956)

World War gave rise to numerous developments and started off the computer age. Electronic Numerical Integrator and Computer (ENIAC) was produced by a partnershp between University of Pennsylvannia and the US government. It consisted of 18,000 vacuum tubes and 7000 resistors. It was developed by John Presper Eckert and John W. Mauchly and was a general purpose computer. "Von Neumann designed the Electronic Discrete Variable Automatic Computer (EDVAC) in 1945 with a memory to hold both a stored program as well as data." Von Neumann's computer allowed for all the computer functions to be controlled by a single source.

Then in 1951 came the Universal Automatic Computer(UNIVAC I), designed by Remington rand and collectively owned by US census bureau and General Electric. UNIVAC amazingly predicted the winner of 1952, presidential elections, Dwight D. Eisenhower.

In first generation computers, the operating instructions or programs were specifically built for the task for which computer was manufactured. The Machine language was the only way to tell these machines to perform the operations. There was great difficulty to program these computers ,and more when there were some malfunctions. First Generation computers used Vacuum tubes and magnetic drums(for data storage).
