I have had problems with my iPod Shuffle 1gig, although I think they are much more involved with software rather then harder. I don't think it shuffles well and I don't think the buttons are very response when pressing them. On another note the thing gets loud real loud, and the battery lasts FOREVER(although for some reason it doesn't seem to diminish if if you change songs, which makes sense for a HD based .mp3 player but nor for flashed based) and it is already so small that I have reached into my pockets and have not found it or could not distinguish it from my chap stick or other junk. I'd love to see them make it smaller although I honestly can say i do not want it to be any smaller or lighter, i like the form factor as it is, they do however need to add a proper hold button because how it is turned on now is well a joke and a hassle. I'm still hoping for a firmware upgrade that addresses the restart from the same song regardless of pausing or stopping half-way through another, faster responding buttons, and a more random shuffle rather then hearing the same 20 songs out of the 250 that i have on there!!!
