The Macbook air is an ultra-thin Macbook at 0.16 inches (4 mm) at its thinnest & 0.76 inches (19 mm) at its thickest, making it the thinnest laptop in the world. So thin… that it can fit in a manila envelope.

It has a 13.3 inch widescreen display, a backlit keyboard & a multi-touch trackpad. The multi-touch trackpad allows the user to reciprocate the same hand motions as with the iPhone - pinch, scroll, drag, etc. There’s also an iSight webcam at the top of the screen.

The Macbook Air comes with an 1.8-inch 80GB hard disk (as in the iPods) or a 64GB SSD.

The Intel Core 2 Duo processor has been shrunk down by 60% to provide a speed of 1.6GHz & 1.8GHz!!!

To make the Macbook Air really thin, you have to shrink down the electronics… & Apple engineers have just managed it!

It has a single USB 2.0, Micro-DVI & headphone jack. There’s also the 802.11n WiFi (248 Mbit/s!!!) & the latest Bluetooth 2.1!

Unfortunately, there’s no optical drive & the battery lasts only for 5 hours. But you can get an optional $99 USB external DVD burner.

The Price:

The Macbook Air is a great piece of technological marvel, with the small processor, built-in WiFi & that razor-thin body…
BUT it’s not enough. It has faults… too many, in fact!
- It has only a single USB port… now it’s up to you to decide which is more important to connect… your modem or your optical drive or the USB pen drive?
- It has no Ethernet port… meaning you can’t network it with your PC Mac.
- The Micro-DVI adapter to this, Micro-DVI adapter to that… is not a solution. We need proper working ports!!!
- To make it thinner, Apple decided to chuck out the optical drive… & instead provided a software that will allow you to use other Macs & PCs burners. But you need to carry around the Remote Disk dvd to install the software on other computers.
- & what happens when those computers don’t have any proper WiFi connection??
- Another problem with going thin is that the battery takes up 3/4 of the space but provides only 5 hours of battery life!!!
- The battery cannot be removed. If it’s dead, you need to bring it back to Apple to replace it.
- & it’s not the thinnest in the world!!! The Mitsubishi Pedion (12-inch screen, Pentium MMX 233 MHz) was 0.72 inch (18 mm) thick! Read here.
- No stereo sound output or input.
- The 2GB memory is fixed. You can’t add more.
- The 64GB SSD is not optional… you’ll need to pay $1000 more to replace the 80 GB with it.
- For the 1.8GHz Core 2 Duo, you need to pay $300 more.
- The price: $1799 (Rs. 54,000) & $3098 (Rs. 92,000). You can get much better hardware at much lower prices. Even the Macbook Pro is not that expensive!

The Verdict:
The only people I know, that are crazy enough (or fool enough) to buy that… are Americans. Apple were caught in between UMPC & laptop… they didn’t know what to make… so they decided to bring out a laptop with the features of a UMPC - the Macbook Air.
On a positive side, let’s assume the Macbook Air is a hardware prototype for next year’s Macbook Touch. They’ve achieved the thinness, how about the Touch?

See you next year, Steve Jobs!
