I had exactly that tablet before, it installed horribly on windows and even worse on ubuntu. the times it actually worked it was a decent tablet though. but it had some kind of bipolar disease so it would only work half the time it got plugged in, and even then you had to connect/disconnect 5345451169times if you wanted to keep working with it, as i type i remember the days i had with it and all the memories pisses me off!
what i did was take it back to the store and blamed the drivers for not working, they let me switch to a wacom bamboo pen and touch small, which was actually a bit cheaper so i got some money back too.
this new tablet of mine is glorious, truly glorious, it works like a charm on windows and it works even better on ubuntu netbook edition, on an actual netbook, the weakest piece of cpu i have ever seen and yet it handles greatly with the tablet, the pressure sensitivity and all of its gadgets, although the touch functions are a bit off, it seems like people had solved those issues but i never use touch so i didn’t bother with it.
there was the very short novel “my tablet memories” by fredrik larsson.
what you should take with you from this is that trust is horrible and with wacom, you will be satisfied even if you buy the smallest oldest cheapest one, so if there is any way you can switch it, you should.
also, i will share with you a tip that i discovered a bit after i got my wacom tablet, regarding what size to choose, myt biggest concern with switching to bamboo was that i had to get a smaller one, because all the big ones are way more expensive and my brain kept saying that bigger is better. but in fact it is not. try sketching some on paper and determine how you sketch, do you mainly use large sweeping motions or do you tend to fiddle with details just moving the tip of the pen?
i would actually be better off with a larger tablet because i like to sweep across the entire paper. even so, i am much happier with my small bamboo than my large trust.
i hope it works out for you and i hope that deep in my rant you found at least some piece of wisdom. thank you for your time.
