Whatever you do, do not make the mistake of buying one of these units today (10/2002) unless you are an antique dealer and you get a REALLY good price.I bought mine in April 2000 for around ...--worked great, good quality. I have not been able to get this unit to work with WinXP--I was using it with a Mac and SoundJam previously. An item as expensive as this with such a short technological life is shameful.Sonic Blue appears to have disowned the Rio500. They claim to have a USB driver for XP but it doesn't work. Period.Bottom Line: I am extremely disappointed by Sonic Blue's disregard for Rio500 customers. I am abandoning Sonic Blue/Rio products just as Sonic Blue/Rio has abandoned Rio500 owners.Caveat Emptor!!
