I went to 4 Wal~Mart's last night at around 11 pm, and found one at the last store on my list, a 16gb model. I paid $398 for it. They have a no questions asked 15 day return policy on all tablets and PC's so no problem getting stuck with it. I checked WalMart today, and they are selling for $99. I am just gonna take it back with the receipt, return it, and buy it back at the $99
Very worse case scenario, they will not go for that, and will just return it for a full refund.
The HP "app store" only has around 2,000 apps in it, and a lot of them are designed for WebOS phones. Meaning, they run in the center of the app, at the native phone solution, and not full screen. That aside, there are a lot of nice features on it. The web browser is really good. It plays 1080p YouTube videos perfectly, and the resolution is really really good. I haven't purchased it yet, as I will wait to see if I can do the return / re-purchase thing first, but it has an XBMC app. This would allow full control of my Media PC. Using the web browser also allows complete control of Home Seer lighting and such.
I would never pay $400 for this thing, with the other options out there, but for $99 its definitely worth it!
@ damage: THANK YOU for the heads up!
