You can set things like the mapping up on a per-application bassis - have a small area mapped for file management, say, and the whole surface for Painter or Photoshop (though since I have a mere A5 UltraPad I don't do so). One feature I like is the so-called "Expert Mode" in preferences - it makes the side switch change the mode of the tip, rather than acting as a click itself. Before they added this I'd use the button to right-click and get the move/copy/create shortcut menu rather than the proper right-click menu because I'd twitched the stylus as I pressesd the button, now I hold the button in and tap the stylus and no more accidental movement (so really, it should be called the non-expert, or maybe the inept, mode :D).
