I'm thinking of getting a tablet, the options are Graphire Bluetooth 6x8, or either an Intuos 6x8 or 6x11. I'll be using it with Photoshop CS and a 20" iMac for photo retouching. Which tablet would be better? Obviously the Intous is a better tablet, but would I really be losing anything with the Graphire? Both are pressure sensitive and the Intous has tilt support and device ID but I can probably live without both of those features.
