Watching everyone's prices for their old ones plummet. iPad 3's are being found for $220-$240, iPad 4's for $300, and at this point, you might as well write off the iPad 2.
Yeah my auction of my 3rd gen didn't sell so I'm going to have to lower my price. Still, between selling my mini, 3rd gen, and Nexus 7, I should pay for my Air.
Thankfully I budgeted for my new iPad Air purchase without factoring in the sale of my iPad 3, I guess. Though I'm still hoping for a semi-decent amount for my Verizon 64gb!
