Ive used 1 before, they do work the same as smartboards, but cant detect hover. For an fps they can be very good for sniping, coz u just tap the enemy and they die, but ptherwise you have to hold your finer down near the centre and adjest it slightly to turn, but while your doing this you wont stop shooting. there ALOT better for RTS games where you click and drag alot. had hours of C&C Generals and UT GOTY at my old college on the smartboards running off my laptop.
