I have to say, had I realised when I bought it that the Mojo would require a separate transport if I didn't want to keep my phone in flight mode, I might have bought a semi-decent DAP instead, anyway (I know that may be heresy). It's not that I'm crazily biased against them- though I do have my reservations about some of the more creatively priced options. Edit: I have been known to take my old simless S3 with me on long (>10km) runs, as an audio source. I leave my phone at home because it's a more modern clownphone and too big/heavy to slip in my little waist pack. Shorter, faster runs tend not to get as boring, so the only electronics used tend to be my GPS watch. If Sansa Clips weren't actually quite expensive now, doubtless I'd grab one of those instead - but since the old phone is just sitting there, I feel it's silly not to use it. Yes, I appreciate that's not an example of Mojo+DAP sans phone- but it's effectively an example of being without my phone for an extended period.
