Mini-post-its. I keep track of my table images with these. If I do something donky or make a move of some sort, I make a quick note of it and put it on the monitor next to the table.

Dial-up modem, with a free provider if possible. More necessary for tournament play when your broadband goes out.

Pee bottle. More necessary for tournament play. Empty Gatorade bottles work well. It sucks being at a final table and having to take a leak.

Compact your datases at least once a week, and defrag your HD at least once a week. I do it 2-3 times, usually, dpeneds on how many hands I'm getting in.
