My Palm IIIc is now approaching 5 years old. Finally the battery is aging and supplying about 1/2 the hours it did when new and this year the screen is not white anymore but an odd reddish tint which clears up after a minute of use.
I've replaced the IIIc with the T|X and would buy either again.
Tungsten C has failed over and over. Palm Customer Support is undoubtedly the worst ever. Please do whatever you can to avoid purchasing any Palm products. My long and painful experience tells me that these products are all severely flawed, and the company will not help you sort the problems out. In my case, the expensive refurbished Tungsten C sent me when my 4th or 5th one collapsed would not synchronize using any of my multiple cables or cradles that had always worked fine with Tungsten C. The company's response: "Maybe you can buy a cable on Amazon.com...." Only masochists will be happy with their Palm experience.
