Just thought I'd give a quick update after having used this machine for a couple of months. 1st off, I'm a very happy Rev A owner. The computer meets my needs in every way and has given me no problems at all. It joins 3 other macs in the household, but the Air is my baby. It's really the only keyboard in the house I use anymore. I have two mac mini's that act as home theatre servers and my old Powerbook is quite happy as an ftp and http server. So my Air does all my day to day Internet, mail, scheduling and promotions. I do quite a bit of photo and other art work on it. I'm doing much writing and research and of course control all my other computers with it. The programs I use mostly on the Air are: Jolly Fast VNC - to control all the other computers Safari - I just don't need another browser Mail - and more mail. I-Cal - always open I-tunes- no storage on the Air I-Photo - Minimal temporary storage on the Air Aperature - Minimal storage on the air Seashore Gimp I-Work- I play a little UT 2004 I run cool books and smc Fan control, but I haven't seen any problems with heat. I do watch some video on it, some flash stutters but everything else I've tossed at it runs fine. The computer looks beautiful and runs perfectly handing several of the above programs at the same time. It came shortly after ordering in perfect condition. I was very pleased that I purchased the computer I did, when I did and for the price I got it. Your milage will likely vary.
