Someone's using an optical pen/tablet as pointing device just now on MyLot?

The reason for this question is that I was evaluating the possibility to ask Santa such device for X-mas, because of my wrist troubles using a mouse, but the fact is that I don't know anybody who uses it and so I couldn't ask for advices in the choice and Pros and Cons... So I'm still using mice and my wrist is still hurting and insulting me... Let me know... if U want. good bye
