I have decided to buy a Sony Clie PEG-UX50. It has WiFi, Bluetooth and all the other features I want. However, every website I go to that has the PEG-UX50 for sale lists it as a "Refurb." What is going on? I heard that Sony is getting out of the PDA business, but have they already stopped making new units? Is there much of a danger in buying a "refurb?" Where would you reccommend I go to purchase a PEG-UX50?. Thanks.
