Between the wife and I, we have owned one or two graphics tablets in the last few years, and I have never been a fan until I switched to a Macbook Pro for my image editing.

Our first forays into the world of tablets started of with little 4x5 versions made by Genius, and had a wire attached to the pen tool that was just too small and awkward to use. That one went back to the box within days (we found it the other day, so if anybody wants it, you are welcome to it. There are no drivers for it though, so you will have to write your own, unless you still run Win98. More or less par for the course when it comes to drivers for Genius Products)
