Again,
the stylus is different from the whiteboard application.  I agree a 
TablePC offers more accurate capture of drawing than a Mimeo or mouse, 
but that's an interface technology and can be treated separately from 
the issue of bundling some (any) whiteboard software with an AG that 
supports collaborative sharing of digital ink.

So I'd love to use a handheld tablet to draw on my 'wb' application 
rather than using a mouse or digital easel, but wasn't really my point.
