I don't know why you are all complaining about the design of the new generation of shuffle, it's amazing!
I bought one and use it at the gym and I love it. It's suuuper small, you have to see it in person.
There is no need at all for buttons on the unit, the VoiceOver technology is great, it tells you your playlists and songs. Also, what I found out is that if you are in a playlist and activate VoiceOver, the name of the song comes up obviously, but then, if you click the volume up or down, it says the name of the next song in order. So essentially you can skip through your songs and stop at one when you hear the name of it.
