After spending a week with the 6.25“x10” Monoprice, my Yiynova and Cintiq remain unplugged and I gave my Intuos away to a friend. The Monoprice tracks subtle pressure variances and small movements with less lag and more crisp fidelity than any of the others. It is, put crudely, fucking awesome, in both OSX Lion and Windows 7 x64.
I have one of these, 10x6.5 I bought about two months ago for 48 bucks. It’s a billion times better than my old Wacom Bamboo and works like a fuckin dream.
