So I have had a few days to get used to my new 13.3" ultimate macbook air I have owned virtually every model mac since the original iMac, and even before (I owned an Apple IIe as my first computer). In the portable department I have owned a 12" ibook, multiple 15" powerbooks going all the way back to the g4 (pismo) and most recently a 2.66 Ghz Core 2 Duo MBP, a 17" PowerBook, 13" Macbook, and even the iPad. In fact, I earn my living as an Apple hardware technician for an independent Apple Specialist store. So in addition I have actually worked inside all of these machines, and many more. In my humble opinion I have no doubt why Steve Jobs stated these machines are the future of notebooks. This is the most spectacular laptop experience I have ever seen. Unless you are editing HD video, doing 3d work or high end gaming, this model certainly isn't laking any power. Combine that with the portability, the elimination of hard drive data bottlenecks, and the battery life and this is basically perfection. I have been using it on and off (50% of the time) for 7 hours just surfing and reading with WIFI enabled and bluetooth turned off and I still am showing 3:50 minutes of battery remaining. It's a perception thing but the battery seems like it lasts forever. Of course, play some flash and watch it go to hell - but oh well. Install Click-to-Flash. Connect it to a 27" Cinema Display - or an HDTV (my choice) - or both (even better) and you have as much desktop real-estate as you need. I couldn't be happier and I highly recommend these notebooks - especially the 13" model as a primary computer as long as it has 4GB RAM. So, to all those on the fence I can only say go for it - and get a sleeve - you won't even need a bag to carry it. Cheers.
