Can't hurt. If it works out, great, if not nothing really lost except arguing over restocking fee which it looks like they'll hit you with.
I'm going to return mine and get a MBP. It's a second machine anyways since I have an Air. I may hold on to the MBP unopened if I can help it and wait to see new Air reviews next week or week after. Then if new Air sounds good, exchange unopened MBP for an Air. If it sucks, keep the MBP.
The Air screen really kicks butt. With the ever decreasing cost of panels these days, I can't for the life of me see why Apple sacrificed the beauty and functionality of the new MB with such a mediocre display. Everything else on mine is as perfect as could be. Very sad.
