I currently own the 2011 13" MBA and was considering getting an ATD to go with it. I've owned it since August, but started using it as my main the past few weeks because I sold my desktop. Currently have it hooked up to a 23" monitor, but would love the ATD haha. I also have a keyboard and mouse I use with it. I use my MBA to study (chrome, powerpoint, word), listen to music (iTunes), iChat, and watch videos/movies. I don't play games or do anything intensive that requires a discrete GPU. I just started a 4 year graduate program and find myself on campus roughly from 8-5. I was looking into buying an amazon warehouse ATD for ~$820, and depending on how much I like using my MBA as a main, I may also pick up the 2012 mini when it comes out. My rationale for this was that I would have the flexibility to upgrade my MBA (and possibly mini) in the future and continue to utilize it with the ATD. But if I'm going to be spending all this money anyways, I was wondering if I should get a 27" iMac instead (even though I dont need all the extra OOMF it comes with). Thanks guys!
