As I posted in another thread, 1st generation ipads can be traded in also. But it'll fall under their general trade in program. Same goes with surface RT and pro. They can be traded in at Microsoft store for credit out on giftcard that can be used towards the newer surface or whatever in MS store. Called the store earlier and found this out.
See this makes sense and whatever I suppose if you hate your iPad, but you can sell them on Craigslist or Ebay for more than 200 if they are Gen2 and up.
