Apple unveiled the thinnest laptop in the world the Mac Book Air. It has a height of 0.16-0.76 inch, width of 12.8 inches, depth of 8.94 inches and weighs around 3.0 pounds. The first time I saw this laptop on TV my jaw just dropped in awe. More so when it was demonstrated that it can fit inside a long brown envelope.
Despite its thin size, the laptop Mac Book Air packs quite a punch when it comes to hardware specifications. The processor of this laptop is an Intel Core 2 Duo processor with 4MB on-chip shared L2 cache running at full processor speed with an 800Mhz frontside bus. It's RAM is a whopping 2 GB 667MHz DDR2 SDRAM. In terms of hard disk space, the laptop Mac Book Air has a 80 GB Parallel ATA Drive.
The best thing about this laptop for me however is its looks. Nobody just can't seem to beat the Mac laptops when it comes to this department - very slick physical design combined with an eye candy OS X.
The only problem with the Mac Book Air, as well as its predecessors, is the fact that it's quite a bit pricey compared to normal laptops. The Mac Book Air costs around $1800 but with specs that would only compare to a $1000 laptop. It's like paying another extra $800 dollars for the looks and the brand name.
I really wouldn't recommend this laptop to anyone who prefer specs better than looks. But if you are willing to sacrifice looks for specs or if you can afford to buy such equipment without any fuzz, then go ahead. As for me, I'll just be looking at them through pictures for now.
