The thing I wish I had in design school, other than sleep, is my 6×8 Intuos3 tablet. I don’t design, let alone touch a computer without one. When I even do just an ounce of design on my Powerbook, whether it’s over the weekend or late weeknight *ahem, right now*), I pack my tablet with me from work. The mouse has been dead to me for almost half a year. I love it.
