I haven't used a mouse since about 1999 when my index finger told me I'd been doing entirely too much double-clicking in my Flash animation job. It's been all drawing tablets since then. I have a mouse that I use on the rare occasion of playing a game that requires you to move the view by pushing the cursor against the screen edges; I have to hold it in a weird, awkward grip because that tendon still starts screaming if I try to use it to click a mouse button.
