The best part is that they have already sold 12 units at $599.99. I swear EBay is the home of morons.
That actually sounds like a smart move. The buyer just emails HP, claims that it was a mistake of some type, and asks for an adjustment. Either HP adjusts to the sale price or else they return them. 90% chance that they get cheap Touchpads IMHO. If I were keen on these, I would try that move. After all, remember that many people who won the Touchpad lottery earlier did so by betting that people like Amazon and NewEgg would eventually agree to price adjust vs. taking a return.
