Hey guys. Currently I have a shuffle for my running and gyming needs. I find it annoying I can't choose different playlists with the shuffle depending on which activity I'm doing (running or lifting) so I'm thinking of getting a nano. I also really want to get in on the Nike+ system. Before I get a nano, I'd like some input of people who own or have owned these accessories to get a comparison. I may decide to just keep the shuffle for running and use the Sportband instead of the nike+ipod system. It seems easier in that you don't have to worry about dongles you just strap it to your wrist, which is a lot easier than strapping an armband on. Not sure which one to get, are there any quality/accuracy issues that set them apart? Anything else I should know? I'm assuming they both work the same, just that one requires a nano and obviously you can listen to your music as you run (although I can do the same thing with the shuffle).
