Pros: Battery, very good sound
Cons: Small screen (don't care!), crap UI
I realize this is ancient news in 2014 but I recently rediscovered my iAudio7 and am loving it. It sounds remarkably good for a "fun"-signatured DAP and holy mackerel, the battery life is incredible. 50 hours? 60? I don't know but it's great.
The secret, obviously, is the super small and low-res screen. But you know what? Fine by me. It's perfectly adequate and once you get used to the counterintuitive UI, it's pretty easy to manage. In a world with ever-evolving tech, this is the rare case of "they don't make 'em like they used to."
