Pen Computing reviews available software for the Tablet PC.
Groove's initial enhancement to support the Tablet PC is the addition of ink chat. Ink chat can be used for simple wireless messaging in a meeting, or you can embed images and other objects in the message, turning it into a kind of whiteboard messaging tool. There is also an existing sketchpad tool in Groove; with the availability of the Tablet PC's pen, the tool becomes much easier to use than with a mouse. Groove seems committed to the idea of digital ink, so future versions of the Groove workspace are likely to include additional ink support.
