I've been lurking around this forum for quite a while catching up on the various notebook threads. So, now I have a question of my own. Currently I have an MBP 2010 i7 / 8GB RAM / 256 SSD, I use it for web design / dev. At any one time I have Photoshop and Illustrator (CS6), Parallels running Windows 7 and Espresso running. It's a great laptop but it's just too damn big. I've been eyeing up the MacBook Air 11 inch (i7 / 256 / 8GB) which I would run through an external display when sat at my desk, so screen space on the Air wouldn't be a problem. What I'm concerned about is the integrated graphics of the Air. The MBP has an NVIDIA GeForce GT 330M 512MB (that burns a hole in my knee quite frequently so I'm assuming the apps mentioned above make extensive use of it). Where does the HD 4000 sit in relation to the perfomance of the NVIDIA? I don't mind it being a sidegrade in perfomance since I'd be gaining the potabilty but I'm worried that it'd be a downgrade in real-world usage. I also play the occasional bit of Black Ops on Bootcamp. Anyone got any thoughts?
