Over the years, I've used a variety of MP3 players, then some better ones like my SONY PCM-M10 that accept .WAV format files. Now I just use the iPhone (and an iPod would be the same, if you had that) for its size and user interface. I do have an iPad3 and love it in the studio, but I don't think I would want to take that to a gig. It's solid enough but still more likely to get broken (or stolen).
