I have a Zen that I was planning to upgrade to 80GB, but with the current file count limitations, that doesn't make sense. If I had heard about the problem before purchase, I wouldn't have bought it.
I'm hoping Creative can & will release a firmware update that increases the ID tag database storage like the new 60GB unit must have.
Aside from that, the Zen is no Empeg (of course). But it's nice, and portable enough for the gym.
I also have an Archos Jukebox 6000 upgraded to 40GB. The Rockbox software really makes these MUCH nicer.
