Some Hobbyist Software titles I would recommend are Reset Doctor, great for finding what app could be causing crashes and to stop random crashes.
Butler is a great addition to any Palm Device - Multiple alarms, an attention grabber, enhanced speed, etc.
Power Hero is an essential addition to extend time between charges - Take care of what is on and when it is on.

Phone Technician allows you multi-task with your Palm OS smart phone... Try all of these, but if you keep them please ensure you pay the developer...so he can continue to maintain these products and introduce better one.
