Yes, I know it’s not an iPad but it’s a Kindle, a video Skype Phone, a clock(!) or a variety of other things. Once they crack it and put android on it, I’ll probably wish I’d bought the bigger one. These were actually nice tablets at $500, but they weren’t an iPad, but for $99 it’ll do.
As you can see, I’ve redacted most of the information below because it changes so quickly. I expect all vendors will be dropping price, keep your eyes on SlickDeals.net, if you scroll down you can see they are even keeping a list of who has them at full price (because they’ll be dropping).
Their servers are getting nailed so be patient. Just click to order and wait until it times out, then try again…
Barnes and Nobel has 16 GB for $101.95 as of 6am Eastern (but they still want $600 for the 32 GB). I’d order one, but I haven’t gotten a rejection letter from my CostCentral order (that I’m guessing was sold out).
Cost Central has the 16 GB for $99 and the 32 GB for $149. 
As of 10 PM eastern Cost Central had 10,000 of the 32 GB and 7,000 of the 16 GB (this is listed on the product pages). It was $9 for shipping (that may vary) and probably no sales tax for 49 out of 50 states.
These were on Amazon Sunday for the same pricing and I spent too much time researching it before purchased it and they sold out (I guess HP had them for that price earlier). So I had a little regret about it, but then I saw these. Even if I get a rejected order message, I’m sure the other places that have them still at $500+ will be dropping prices, so keep your eyes on that SlickDeals link above, they’ll keep it updated with who has it in stock.
You can get Touchpad specs and overview at the HP Site.
Supposedly PCmall and MacMall have them, but their sites are even hit worse, 32GB or 16 GB.
In case you are wondering why the price is so low: HP is spinning off it’s hardware business and discontinuing the mobile / tablet (hardware) business. I think these devices just came out in July 2011.
UPDATE: I actually ordered these from two places, the one canceled after a week, the other still says it’s expecting a shipment (but I’m not sure from where at this point). So it looks like I’m not getting one…
UPDATE 2: Early November, the second company sadly canceled my order. Looks like it’s time for a Kindle Fire!
