After a year or two, the power adapter broke and I took it back to the store where I had bought an extended warranty. They offered $186 IIRC as a refund based on the age of it, saying that I should have been able to get something comparable for that much at the time, given the inevitable progression of technology. Palm, in reality, was still selling the same old TX for the same price, I think it was $300.
My issues were pretty much all software anyway. They had the capability to release software updates, but they chose to avoid releasing updates except for the daylight savings change.
Massively. It was good on paper but Palm never updated the software on it so the browser was piss-poor, network implementation felt last-minute, and they forgot to design the software for the hardware - mainly, the touchscreen calibration utility hadn't been updated to deal with the lower part of the screen (320x480 vs 320x320). My digitizer was a bit off, evidently, and the calibration utility should have let me correct for it, but it didn't, so it was impossible to use the onscreen keyboard. I had the choice of buying third party software to recalibrate the entire screen area, or correct for the error when typing by always tapping above the key I wanted.
I went through 3 Palm OS PDAs (m100, Sony TJ35, T|X) and I'm glad Palm is dead. Devices like the iPod touch are the new PDA.
Things equal to nothing else are equal to each other.
