I bought the $50 10x6.25” tablet without hotkeys in October of last year and have been using it almost daily since then. The stylus is still on the first battery!
I have successfully installed this tablet right out of the box on Windows XP, Vista, and 7 (64bit). Just make sure you install the drivers BEFORE plugging in the tablet.
They blow Graphires and Bamboos out of the water, and are a lot cheaper. For $10 more than the smallest, cheapest Bamboo, you can get the largest (12x9”) monoprice tablet!
If you’re looking to upgrade from a tiny Wacom tablet (like I was), buy a spare, or want to try out a tablet for the first time, these are a great choice!
