I hate mine also (grey poly on black ipad). Cant wait for the book case cover. When I called Apple to return my cover, the lady said for me to keep it and that she would credit me. I guess it was cheaper than having to deal with the return, shipping etc.
I am returning my blue poly..just stuck in the mail. BUT I made the mistake of doing it online so no freebies for me. In fact, it said I would be deducted 10% restock fee. I talked to "Thomas" on the phone on Wed who after putting me on hold for 20 mins to talk to a supervisor, "assured" me that they dont charge a restock fee. Personally, I dont think half of their reps know what they are talking about. I would make sure to follow-up on that promised credit.
