This is your iPad. This is your iPad two weeks before the new iPad3 launch.
Scary.

NextWorth, the company that gives you cash for your "old" electronics, came up with this graph, using stats from ebay. As you can see, 2-3 weeks before the launch of a new product, the last generation declines in value. Expect to see this pattern before the new iPad3 comes out (rumored to be March 7.)

To help consumers trade-in early to maximize value, NextWorth locks in values for 21 days. Values quoted today hold true, as long as the device is dropped at UPS by the 21st day (free shipping label provided).

They inspect it and then pay you for it, so you can put it towards the next model. If you're gadget-fiends like us, you'll end up doing this a LOT.
