It's already out on the 'deal sites' with thousands of comments and over a million views. People are buying them through HP Academy and HP EPP. Amazon had the lower price briefly then went back to $398, probably sold out whoever offered it at less instantly. The 16GB is already sold out at HP direct. By 7AM they won't have any 32GB left to sell either.

Edit: HP.com sold out of all models in around half an hour. Every other store that had it at the reduced price sold out in minutes. I suppose it's impossible, but gotta wonder if anyone at HP will be reconsidering the decision to dispose of WebOS when their TouchPads are sold out nationwide in less than a day.
