HP is manufacturing up to 100K more, but honestly, most are probably going to backorders (as in the deal onSale negotiated with HP). I lucked out and got one from Best Buy and am glad I did.
Plus supposedly this week all of the HP employees get a crack at them, I think yesterday was the day for that.
I just keep randomly hitting websites hoping for the best each day. Office Max and Office Depot supposedly had their links up for a few minutes until SD posted them, probably selling off orders that got returned. Last week QVC had a bundle, the case, the charger and the touchpad for $200, that sold out in 30 minutes. Fatwallet posted that one.
So it is possible, you just need to get lucky. I saw one on amazon the other day for $199, so hopefully more people will get desperate and start selling them cheaper on ebay and amazon, now that the initial mayhem has subsided.
