Unless this comes in around the cost of a regular netbook (~$320 USD) then I don't really see the point.
Netbook:
Flash: Yes
Replaceable battery: Yes
Touchscreen: No (for the most part)
Real keyboard: Yes
Bluetooth: Yes
Tether: Yes
Unless you have a dying need for a 10" touchscreen and the ability to blow up an iPhone application to super pixel size then I really don't see the market. You could argue it as an ebook reader, but the price points they have set in place make the Nook, Kindle, and others look a bit more appealing from the $9.99 and under book list.
Overall, I give it a 9.5/10 on the "solution looking for a problem" scale.
