I've never owned a PDA before, but after realizing my poor organizational skills and many tasks for classes after my first semester of college, I'm considering buying a Palm TX. It's sleek, thin, simple, not windows, wifi, great screen, etc. The perfect pda for me. As an apple customer, I'm used to updates coming all the time and I'm weary about buying something that was released over a year ago! How often, on average, does Palm update their PDA's? Should I wait for a newer model?
