Yup!!!
Wacom Tablets Rock!
If you think you draw more using a hand wrist action I'd reccomend either Intuos 6x8 or 9 x 12 size tablet.
If you draw using more of an arm movement then either a Intuos 12x12 or 12 x 19 tablet.
These are going to be much pricier, though.
a friend of mine tried my 6 X8 tablet, but because he is used to drawing more with his arms a larger drawing media, he bit the bullet and splurged on the largest tablet Wacom makes.
The way he uses this tablet is incredible. He draws on this thing just as if he was drawing on large actual paper surface.
I wasn't ready to spend that much so I purchased a 9x 12 tablet and modified my drawing techniques to fit the working tablet area.
Wasn't that much of a big deal for me as I draw on a lot of different size media, anyway.
Could, like my friend, definitely matter, though.
IMHO
