Good although software can be a bit temperamental.
I'd already bought a Zen V plus and was very pleased with it so went for the 60GB Vision M. It's still going strong after 2 years. Battery life is excellent for both music (15 hours) and movies (5 hours). I also bought some cables so it can be plugged into a TV when I'm away. It's kept me going for 100's hours while flying or away from home. Picture quality is excellent. It's worth investing in a mains charger and a decent case and also while the Zen earphones are OK get your own. Transfering data is pretty straight forward drag and drop. A bit frustrating initially although once you get the hang of it and you have conversion software you a comfortable with it's simple.The only negative thing about it is the software/hard drive which does seem to hang up sometimes and you end up having to reset the machine (this takes around 10 minute to rebuild/reindex the files).
