I have a Compaq iPAQ 3970 PDA. It was given to me about a year and a half ago by SMU because we were going to write a PDA-based ticket writing software for the SMU police department. I wasn’t going to write the software, but as a web geek I was supposed to provide support and knowledge.
The project never got off the ground.
Now I use the PDA to be my Outlook calendar, contacts, and task list when I am not at the office. It’s incredibly useful for this.
My favorite use is a gym workout tracker. The PDA comes with a scaled down version of the Microsoft Excel spreadsheet program called Pocket Excel. After I use each exercise machine at the gym I jot down the weights I used and how many repetitions I managed into my spreadsheet. (Click on the spreadsheet to see how wimpy I really am.) Over time I will graph my workout results to see if I am improving.
