Hi Andras,

I have a a Wacom bamboo fun with sliderpad and
4 buttons(programmable)and it works great with
artrage (with some exercise)
I use it in 3d-coat and Silo,but not in Moi

The simple version is the Wacom bamboo without
buttons,no eraser tip
It's pressure sensitive(512 levels)

I have read that the Intuos series have 1024 pressure levels
and can use an optional airbrush(not a real airbrush)

The next tabletpc i will buy is the HP Touchmart tx2 NotebookPC,
which you can use with a pen or your fingers(yes it cost)
