Query: Poor product reliability and customer service

This is my 3rd palm pda. I had this one for less than 3 months before it completely died one day. This was 6 weeks ago and I have not yet received a replacement. The customer service is poor. They seem to have unmanageable manufacturing delays. The ship date continues to be quoted and moved out a week or two at a time. If you rely on the portability of your data, do not get this product. By the way, purchasing the additional warranty coverage from Palm has not helped my situation at all.
