Query: Palm m500 - Be Aware

I purchased a Palm m500 from another retailer, and was unable to sync the unit to my pc. After several calls and 15 days, I was finally told by palm support that my unit was defective. They advised me to return it to the store for a replacement, or to send the unit and cradle to Palm for a replacement. The store no longer carried that product, and upon further investigation and direct questioning, tech support at Palm then revealed to me that I would only receive a refurbished unit from them. It would appear that there is a known problem with the Palm m500, as Palm support has advised me they no longer make this unit, and all the stores that I have contacted will no longer be carrying this particular unit.
