Okay, after reading all of the M10 love on this forum, I'm definitely interested in checking them out the next time I need a new recorder. My question to folks here: I currently have a pair of iRiver 320s, with Rockbox installed, which have served me extremely well. Aside from 24-bit recording, are there any other major improvements I'd notice with an M10? Or can I happily save my pennies until one of the 320s gives up the ghost?
