So... I learnt the hard way that you shouldn't drum on your desk with your Wacom pen. I actually decided to replace my tablet entirely (a friend is going to buy it and try to fix the pen) with a Wacom Pen & Touch.
I'm assuming though that the touch functionality won't work with Skritter as you can't 'write' with the finger movement? Is anyone else using the pen & touch - if so what do you think of it?
