My lifedrive also falls in the lemon category, and frankly so does palmInc in general. I second the motion as to instability. The only fix is to wipe your data and never install third party apps which makes the lifedrive an expensive paperweight as the native apps just don't cut it.
Palm warranty and particularly their extended care package are anything but what their names imply. Essentially, you will receive no hardware support unless the lifedrive was damaged before it got to you. Everything else is your fault (According to the tech support reps). Moreover, when you come across the frequent limitations in the native software (e.g. VersaMail) and discuss the problem with tech support, they will quickly blame the problem on the server you're connecting to, the service you're trying to use, or anything else but a development flaw.
Then there's palmOS. Any application that causes an error (e.g. null/invalid pointers) will always result in data loss. You will quickly find that other application data has been trampled or lost with the result of application instability. Frankly, any OS that reboots on all errors is a shoddy OS. It reminds one of Windows 3.11.
In short, don't buy palm. Its a waste of time and money.
