Although it isn’t a real play thingy… It will be rather useful to me!
Anyway, I always wanted to have a drawing tablet for my computer. Specially after someone showed me how handy such a tablet can be with processing pictures. Oh sure, everything is also possible with a mouse. But with such a tablet things will go easier and faster (for instance you can jump from one side of the screen to the other, while with a mouse you have to drag the cursor to the point where you want it. Now it is just one click with the pen on the wanted position and the cursor is there).
Many functions are very easy to access. But maybe even most important, when making very precise and small adjustments to a picture the tablet will be way more useful as the mouse.
But I admit, it will take some time to get really used to it. But that is okay :).
