As a photography student I use Photoshop a lot and have started looking into buying a drawing tablet (believe it or not, I've been using my Powerbook's trackpad up to now!). I aim for something which will be good enough for professional use (when I get there) as opposed to buying something I'll outgrow in a short time. At the same time I don't have money to burn and want to avoid using $$$ on features I don't need or won't even notice. I read somewhere that the lower resolution of the Bamboo range means that I get the occasional "glitch" or involuntarily "jump" of the mouse pointer while the Intuos are rock steady. I certainly don't want that. Is that the way it works? And what about size? What's the difference between getting a large and small tablet?
