my recommendation... buy one that is proportional to your screen.
if you are using 4:3, then get a 4:3 type, if yours is 16:10, then get a 16:10 one. Or simply put, get wide one if its wide screen.
Then if you're using dual monitor, just set the tablet to 1 monitor, you still have your mouse. Most of the time, you won't be using both screen to draw together. So if you're using 2x 4:3 monitor, no point getting a wide one.
As for size of tablet, buy a tablet approximately 1/4 or 1/2 the size of the monitor. small screen lower res, bigger screen higher res, so does tablet. if you buy a tablet 1:1 with the monitor, you will tire yourself out very fast, unless you are using it for extreme precision, or for tracing large prints.
i bought the S model. It's more than enough for photoshop editing. I hate the big ones, have to move all over the place. Small ones just have to move your wrist. i'm lazy that way.
How do you find your Intuos4 tablet? It supports 2048 level of pressure sensitivity (the highest in the tablet industry technology) which give a more nature and realistic pen feeling, so do you find any different? (please take note not all software support 2048 level)
You have bought the S model is due to portability or mobility reasons (from my advice)? ;p
Can't say I can feel the difference on the pressure sensor but feels realistic enough for me. I not a real good judge on this though.
Sorry mate, I bought this long before I saw your post. For me mobility/ portability is not the issue. I like small movements.
still thinking whether to upgrade my Intuos3 to Intuos4.......... :think:
If your Intuos3 is in good working order, keep it. Don't waste your money upgrading. Don't get caught in consumerism. A few more buttons and pressure sensitivity don't add to your productivity, but of course if you get big bucks for your work, then I've got nothing to say. Even then, it makes no business sense spending for the same function.
