I got the 256 gig 9.7 pro. I had the 12.9 inch at lauch, returned it because it was too big to be really portable. In hindsite i regret that choice and now want to upgrade to the 12.9 When will apple be taking those in as trade ins? there not on there recyclable site yet, and other places are low balling me. Think that will be before launch date or after?
