Anyways, the way I see it, tablets are one of the most important human->computer interfaces. The keyboard of course takes spot number one, the mouse spot number two... tablet gets spot number three. It just gives you that extra control that you might need for a myriad of things. Not just drawing. Could be with 3D modelling, or animating, or tweaking graphs, or... any number of things you might encounter whilst using computers. Well, I've personally been really grateful on a number of occasions, for having a tablet. If my desk wasn't so messy, I would always have it there...
Do what I do; multi task. As I set here on ZU right now I am also studying for a final exam for a class I find boring! And attempting to bring myself to care. I've gotten to the point of "I want a B- in the course. I got to do well."
Yay for the bigger tablet! (Though a shame about the delay)
A lot of people swear by the medium sized tablets, it's well balanced. So you'll be taking a smaller risk with it, I guess. Although the price is higher, so that sort of counters it...
Oh well. It's definitely worth the money.
