I’ve been using Palm devices since the original 3Com Palm Pilot debuted in 1996. My fifth and final Palm device (thee PDAs and two phones) was my blue Verizon Centro. It was a great phone. I had it loaded with dozens of applications that I had been using for several years. It synced with the Palm Desktop, which had been continually upgraded since that original Palm Pilot.
But the Centro was just a phone with a lot of local apps. Email didn’t work very well; neither did the clunky browser; the screen was too small anyway. It connected to the Internet with all the speed and convenience of a 1200-baud modem. So I waited patiently for the Palm 
Pre to become available on Verizon. But by the time it arrived, it was too late; the Droid had gotten there ahead of it. So after some indecision (Pre or Droid, Droid or Pre), I ordered a Droid from the Verizon web site and vowed to activate it immediately upon delivery.
The transition turned out to be almost as challenging as replacing a desktop PC. All those Palm OS apps would have to be replaced or done without. Fourteen years of accumulated PIM data – calendar, contacts, and dozens of memos – would have to be migrated, as would my Palm-compatible security vault with 140 password and account entries. The Palm Desktop itself would be useless and the days of a single click keeping handheld and PC in sync would be past.
