On the heels of the death of the Courier, there are now rumors circulating that the HP Slate, a tablet running Windows 7 instead of a phone OS, has died, too.

...according to the source, HP isn't thrilled with Windows 7's performance on the tablet. The Slate — which was officially unveiled in January by Steve Ballmer himself — had a rumored price of $549, and was supposedly launching in June

HP just bought Palm, though, so they'll probably be announcing something similar with their own OS eventually. This leaves pretty much all eyes on the Notion Ink Adam. Who knew it would be so hard to make a tablet computer?
