I am looking at the Wacom Graphire 6x8 Bluetooth tablet for my birthday. My main uses for it would be mainly jotting notes down in school into my iBook, and some very light work for fun in Photoshop and with my digital pictures. Is this right for me? I would go with the much cheaper 4x5 model, but I need the Bluetooth functionality. I would also get aquatinted with Apple Inkwell because it seems very useful. Does anyone have one, and is this the right product for what I want to use it for?
