I've enjoyed a Palm T3 [bought used] for 5 years; it's been fast & reliable. The 900 mAh Battery is inadequate for the 400 mHz Intel xScale processor, and the battery is NOT user replaceable.

With the power getting steadily weaker. I downloaded PXA Clocker, thinking that some Underclocking of functions and programs, could extend battery life. NOTE that I did NOT as yet change anything. Two days later the unit crashed totally, and would not even respond to a Hard Reset. RIP. Feedback welcome.
