Microsoft wants iPad owners to switch to their Surface tablet and is offering a pretty good incentive. The company will give a minimum $200 gift card to shoppers that bring in their gently used iPad 2, 3 & 4s.

The gift certificate is good at the Microsoft store and the goal is to get these former iPad owners to purchase a Microsoft Surface tablet. The Surface is only $349, so the trade in would give you a new tablet for as little as $149. (The Surface Pro is $799.)

The promotion is running through October 27th and it is only good in Microsoft retail stores in the US. One trade-in per customer. Follow this link for more details.
