One Palm OS program I've missed having since switching to IT is one that keeps track of frequent flyer programs and miles. Since I couldn't find anything like that, I wrote my own.

First Alpha release is available for download here:

It requires that you have Python 2.5 installed. All data is stored in a sqlite database.

Click on the properties tool button first to add programs, then add flights and other activities.

I used Python and GTK. Both were new to me so I'd welcome any comments or suggestions.
