A lot of people don't remember Palm OS, but as someone who owned a Palm TX device, I have most fond memories of it. And I still consider it the best handheld device that I had (including my current Nexus 4) in terms of both design and UI, and user control, and battery life, which lasted up to a week! It was a real bummer to see it go. I still miss it.
I lost my Android phone, so am currently using my wife's old centro. It's amazing how many things it does as well or better than the android phone did (battery life being the biggest one).
You may want to check one of those "lost/stolen Android" apps for your next Android. They allow you to control device remotely, find out GPS location, erase SD card, etc. Quite useful.
