Tablet PC Team Blog : Windows Vista Feb 2006 CTP Rocks on Tablet PC!
the cool new Input Panel, which docks to the side of the screen. Pen Flicks (which greatly mitigates the pain of using a scrollbar with a stylus). Journal and InkBall are there. Ink Watson and Handwriting Personalization. Support for Network Projection. And there's Mobility Center, a one-stop-shop for managing power settings and sync'ing files. Also, a special surprise -- a lightweight version of the Snipping Tool powertoy is now included and installed by default, on Windows Vista! (Just start/run "SnippingTool", and have at it!)
