To up the tablet rumor ante, seems that MS will up the Apple ante with an HP tablet, possibly announced during the Ballmer keynote at CES today. This was posted here almost four months ago with the story about the HP Courier with the great video of it's use helping a designer work on a new project.
Guess this is where we (might) see if the promise in the video has been fullfilled! Maybe keep an eye on #ces or watch the live keynote stream (6:30pm PST), though I'll update this story if anything interesting happens.
This all said, until the (rumored) Apple Tablet/Slate/MagicDeviceThatDoesEverything is shown at the (rumored) media event on the (rumored) date of Jan 26, I don't think anyone is going to be buying anything, just in case the (rumored) tablet is as awesome as it's (rumored) rumored to be!
