i think you meant dedicated video (or graphics) memory? not a major mistake, but for the sake of accuracy...integrated Intel HD Graphics 3000 with 128 MB of dedicated system memory and 4 GB of RAM.
There's people like me who have a self build monster of a desktop, watercooled and all, and yet I need something portable to take to college classes. The MacBook Air is sufficient, it can run AutoCAD, Inventor, and Altium Designer pretty well which are the most demanding college apps I'll ever need.So what, the new bandwagon in pc manufacturing lingo is "ultrabook"? After tablet and netbook from the last two years?
Every 2 years your new laptop is an ultrabook. They get smaller for a reason.
Also, Apple tried the slim thing. I have tons of friends with macbooks, but none of them have an air. What are you going to do with a slim laptop, its not like you can fit it in your pocket.
Or are you just gonna slide it into manila envelopes?
