The first casualty of the tablet wars.

HP is clearing out their HP TouchPad 9.7" WiFi Tablets with 16GB version being priced at $100 and 32GB version being priced at $150.

HP is discontinuing the tablet, so the support/update on the software and hardware side is uncertain.

At those prices they are already out of stock on the HP website, but expect major retailers to start blowing them out at cheap prices soon.

THIS IS NOT AN ANDROID TABLET AND THERE IS NO ANDROID PORT AVAILABLE AT THIS TIME.

Note: BestBuy has 270,000 of the devices – and has so far sold a paltry 25,000. And BestBuy hasn't even start selling Touchpad at $100 yet, so almost quarter million stock still available.
HP TouchPads failing to sell, lots left at Best Buy

They're sending them back to HP. you can assume that HP will try to sell them again at 100$ at some point or just landfill them.
