MacBook Air
After working with the Air for a while, and comparing it to my other macs, I must say I am thoroughly impressed. The SSD yields far greater benefits than what is typically reported in reviews, and while I don't really believe that any 64GB storage device is worth that kind of money, this one comes dangerously close.
It is fast. Really fast. For very many things, and indeed most of the things I do most often, it is significantly more responsive than my MacBook Pro (2.4ghz, 4gb mem, 7200rpm). The difference in CPU and GPU speeds are hardly noticeable, unless I start playing heavily with Aperture or the likes. That said, Aperture 2.0 is a joy to use on the Air, and considering I was using 1.0 on a first-gen MacBook, this one sure compares favorably.
It is also "just the right size". On the standard MacBook, the screen seems small for the size and weight of the machine. Kinda like on the PowerBook 12" - that one would be even sexier if it were half as thick. On the Air, the screen size matches the size and weight on the machine in such a way that I have no objections any more.
The screen. It's bright. And I successfully used it outdoors with the backlight turned to zero (that is, off). I imagine I could spend quite a few hours on the balcony having only the sun to light up the screen..
What can I say? So far I love the Air. Also the fact that I had to get a new bag for it; the backpack I use for lugging the Pro around is far too big for this one. The shoulder bag is so small most people won't even guess it contains a laptop, charger, and an assortment of external harddrives, USB stick and cables.
