Recently I've been playing games on my laptop far more than my desktop, XBox or Gamecube. My nice new home wi-fi network has really given my laptop a new lease of life. (Medieval Total War, NeverWinter Nights and now Starfleet Command 3 are the games I'm playing most). However I'm starting to find the trackpoint (the nobbly bit in the centre of the keyboard) a bit limiting and fancy a mouse or trackball. Of these a trackball seems a more sensible choice as I won't need a flat area next to me on the couch. But are they any good? If so, which one? And if they are crap, can anyone recommend a good, compact (preferably optical) mouse for a laptop? Thanks.
