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.
