Query: Buyer Beware

As a loyal Palm user for many years, I am disappointed to report that Palm's customer support is the worst in the business. The m5xx series has had a host of synching problems and Palm has been totally unresponsive. Yes, the product has many appealing features, but wait till it stops synching and you try to get the problem resolved through Palm. Good luck!
