I've been going through many threads and can't decide on a particular setup so I thought I'd open up a thread and get some opinions. I'm currently doing my masters in aero. engineering and also fly planes on the side/am working towards my commercial license. After I'm finished (in about 4 months) I plan on potentially doing med. school and continuing to fly. I've currently got the 27" i7 iMac at home which I use quite often, but can't decide on whether or not to get and keep a 11" Macbook Air (upgraded 4gb) or iPad 2 (64gb wifi) (I picked up both and have about a week and a half left to return either one). I've been leaning towards the air since it seems to be the more versatile option, but on the other hand since I have a regular desktop/full mac at home I feel like having something low power on the road to be the better option.
