I have one in my pocket right now! I have the lime green one...
I LOVE IT.
Good points:
The sound is * FANTASTIC * -- Loud + Clear
Software is good
Small, solid, light
Battery life is good ( cranked all the way up I still get 3-4 hours)
You can remove the battery.
Bad points:
The touch pad is very very sensitive, even with the sensitivity turned way down.
The menus are slightly confusing, even after owning it a month.
The battery should only be removed when necessary! I received 2 batteries with the unit, but have decided to only use 1. The back of the unit is "fragile" and I have to be very careful putting it back on.
The earbuds fall out of my ears
Overall I still favor it over the IPOD - Tad more storage and better sound.
