Finally saw the Gravity today, it will definitely be worth the wait! That said, I'm still contemplating trading my AT for a GT. I have a loaner that I absolutely love, and I want to tell them to keep my AT and send me a bill for the difference. Wondering if anyone has done this, is it at all feasible, or am I being dumb to do this ahead of the Gravity launch? I know I'll take a hit on the trade in, but I'm not sure how much...
