Actually the sony passed its first test. Took it out for a run, it was loud, clear, good quality, no weird problems on random, was easy to load, drag/drop, just didn't have a case so I stuck it in my pants for 17km and it got really sweaty.
If I can find a decent case I think I'll keep it. Battery life says 24 hours. Although I'm confused how a case will work with the earphone plug on the bottom.... odd.
