I ordered the Visor platinum based on speed, memory and expandabilty. I'm not disappointed in any of these criteria. However, in synching to MS outlook, it deleted my entire address book and calendar on my laptop. It was not recoverable. On top of this, I was only getting 4 - 6 days battery life even when it was used very little. I emailed Handspring requesting help but never heard from them.I returned the Handspring and ordered a Palm Vx. I anticipate it will perform as well as the Handspring but do look forward to longer battery life. I also don't anticipate any need for things like the Handspring expansion modules so expandability is no longer important.
