I thought,that you would need to relate the size of the graphics tablet to the size of the final artwork,but finance forced me to purchase a smaller one than I originaly intended.It turns out that was a good move.I have the Wacom Intous 4x5 and its brilliant to work with and I can just pick it up and rest it on my knee or leave it alongside the keyboord without it taking up too much room.If your into "painting" with the computer its like getting a whole new improved version of Photoshop.
