I received a nice new 11" Macbook Air a couple of weeks ago, to replace my 15" Macbook Pro. I cannot say enough positive things about the switch. The Air is an amazing piece of computer.

The defining form factor of the machine (aside from the air-thin profile) is the screen size, and just before it arrived I had a pang of anxiety: would the screen be too ridiculously small? Would it be unusable? It arrived and, thankfully, this was not the case.

The 11" screen has a resolution of 1366 x 768 pixels and I find this most noticeable in the height- you need to scroll a bit more on websites and in documents. Other than that though, the width is perfect for most uses.The screen also has less glare than the Macbook Pro, meaning that on sunny days I don't have the eyes cut out of my head.

I got the 128gb capacity with 8gb of RAM and it is super quick. Startup is 15 seconds and the whole system seems sharp. I've been using Textmate, Illustrator CS5 and Photoshop CS5, concurrently and without a hassle, for the last couple of weeks.

I think, for me, it's probably the best laptop I've ever owned. I had a couple of 12" iBooks before and I found their size to be really good, but they were a really heavy machine. My 15" Macbook Pro was a decent weight, but physically huge.

The Macbook Air is as light as a feather and has a tiny footprint. If you need a portable computer, I can not recommend it enough.
