1gb in hand. it's for my mom. but until she gives me her cd's to put onto the shuffle, i'm tinkering with it. the battery life is excellent (better than expected). i would say it lasts about twice as long (maybe more) as my 3g 15gb ipod.
my mom listens to chinese music (and i cant type chinese if my life depended on it). a screen would be useless if it's "track one/ track two" etc.
my mom isnt a techno person. the shuffle's simple controls are fine. she wouldnt enjoy going through all those menu's either. if she likes a particular song, i'll just put it near the top of the playlist for her. itunes integration is great. it makes it easy for me to sync her shuffle and my 3g, keeping the libraries seperate. the size is what made her want it. even a mini would be too large (she wants to take it to work and have it in her workshirt pocket, the mini and fullsize ipod would not work out well).
the easy controls makes playing/rewinding/fastforwarding extremely simple to do. i have used it for 3 days now, and i love how it weighs so little and is so small, it seems to dissapear in your pocket. you forget it's there. the controls are easy to hit without looking (unlike my 3g, and any other ipod for that matter).
it's perfect for her, and me as well. i'm tempted but i dont want to waste my 3g ipod which i picked up in august.
