well actually some of the music programs i use are pretty intensive. reason and ableton live...they basically make it like having a room full of audio equip except all on your screen. and when you get a lot of those parts working at the same time the more ram/faster hd def helps. it doesnt bottleneck the cpu
edit: and i used to have a 1st gen shuffle. i actually love the look/feel to those. i loved it for skateboarding. if they made a slightly smaller/diff version like the 1st gen with more capacity id probably get it for skateboarding/snowboarding.
