My Powerbook G4 hard drive was dying and one of the IT folk where I work (why do they always keep the computer gods in the basement?) tested it and told me I needed a new drive and suggested adding memory. I bought the drive and memory and he installed them, and never asked for a dime. This was the first time I've had someone at work fix my computer and I have no idea what would be an appropriate "thank you" for his skill and time. Any suggestions? Thanks!
