With a small desktop, my tablet, wireless keyboard and monitor are crowding each other out. What sort of desktop configuration works for you? Keyboard tray? Tablet on tray? Keyboard to side? Where does mouse go best? I'm trying to figure out a good configuration. Seems like ArtRage and other programs call for many keyboard shortcuts. How much use do you make of your programmable tablet keys? Does even an experienced user need constant access to actual keyboard keys?
