Sure, Gates announced the next version of Windows XP Tablet "by the middle of" 2004, but in the near future, Waggener Edstrom's Tina Warner tells me that the Tablet PC 1.7 SDK will ship with the PDC post-show attendee kits "so timing may be another few weeks." I can't wait!
Oh, by the way, apparently all of the hand-wringing about Tablet adoption has been off-base: "A lot of vertical applications, a lot of horizontal applications, and now close to a half a billion users of the tablet who are very, very committed users." -- Bill Gates, Comdex 2003.
