I may get bashed posting in this thread, but I have a Samsung I500 from Sprint. I realize it only runs Palm OS 4, but I gave up carrying a Visor years ago because I don't carry a purse, and I didn't want to have to pocket both a cell phone and a PDA. The Treo is still way too big. Until Handspring figures out to start offering a clamshell design, I have no plans to switch.
