I'm ready to buy an ultimate 13" Macbook Air for architecture grad school; I'll be using it for AutoCad and Photoshop mainly with some Revit on bootcamp and maya when needed but doubt I'll really use it. I was originally thinking of getting an ultimate 15" MacBook Pro but can't justify the price for a computer which will soon possibly be re-designed. The Air's size fit my needs comfortably, I prefer the slightly smaller screen albeit with a pretty high resolution and find the optical drive to be a thing of the past; in short, I truly appreciate the Air's ergonomics, specially since I'll be moving around quite a bit. This will be a significant upgrade over my 2008 Vaio FZ-340E with a crippled GPU. The Vaio runs the programs I mentioned well but not without some hiccups at times and if the Nvidia 8400M GPU survives (as I have made slight modifications to keep it working after many failures) I'll be running Revit on this instead of doing bootcamp on the Air. I won't play games on the computer either so graphics is no big concern. So, how good or bad is the i7 13" Macbook Air? I've read some reviews but not from everyday users. I'm mainly concerned about the ram but my current 3 gigs run well so I expect the 4 gigs to be an asset. What kind of speed can I expect from the Sandy Bridge i7, what are it's pros on the Air? Thanks in advance.
