Software wise the player is in great shape and has a TON of cool features. It's main problem was a weak headphone jack that was prone to break after just a few months. I say "was" because supposedly it was fixed with the latest models but only time will tell.

this link to get to the creative forums. They have alot of good info there.
The latest firmware got rid of the power drain while in standby problem the player was having and that was the last major software complaint I know of.
