right now i'm using an A6 size wacom tablet on 12"ibook and 17" imac.
i'm considering upgrading to a 20 or 24 inch imac. would i also need a bigger tablet to be working more precise?
or how about if i buy the 20 inch imac but add another screen.
how does that work with a tablet?

thanks,
maarten

Not sure about the dual screens.. but a bigger screen shouldn't make a difference. The tablet detects the screen size, and sets itself to have a ratio to that, so everything stays even.

Personally I use a 9x12 on several different screen sizes from 17" up to 24" with no problems.
