Hi all, My apologies for creating another "is the Air for me?" thread, but I haven't seen this kind of question answered on other threads. I am a graduate student in the social sciences who does a lot of basic web research+ word processing. I also need to run windows in a virtual machine with processor intensive statistical estimation software. All this runs fine on my late '07 MBP with 4GB RAM. I get a little lag sometimes when I have everything going at once, but it's nothing more than a hiccup. In the future I expect to do a little video editing. Probably just cutting out relevant clips and pasting into PowerPoint. I will probably carry my computer most of the day 2d/week and move around a lot the rest of the week. A 15" MBP is too big. Do you think I should go for an Air or a 13" MBP? Wait? Thanks very much in advance for any advice!
