That is a good point.
In considering 6x8 versus 6x11, consider your display. If you have a
wide screen LCD, you probably want 6x11. If you have a 4:3 LCD or CRT,
you probably want a 6x8. If you get a 6x8 (or 4x5 or 9x12) and you have
a wide screen, it is possible to configure the driver to only use a 16x9
portion of the tablets active area, which is what I've done since I have
a 6x8 and a wide screen LCD.
I normally use my tablet on a laptop (1400x1050) with a secondary monitor attached (1280x1024) but set up the tablet area to map to only the one screen. If I set the 6x8 tablet to cover the whole view space across both screens it is quite hard to work with accurately.
