I still say it's too expensive.
It ain't flawless to me, or I'd have kept it.
Noise+hiss, UI not snappy, folder browsing mode on DP-X1 is near instant, try A to Z with the scroll bar. Even my Cowon Plenue D beats the ZX2 in that regard. The ZX2 ain't lightweight or small, but it sure feels rugged.
It has the best battery for android streamer daps (take note competitors) but it is not endless.
AR M20 costs half, is less noisy (ZX2 hisses a lot), has half the battery of the ZX2, but it' still more than the other stream daps.
How much longer would App streamers support Android 4?
I know you can find the ZX2 cheaper elsewere, but official Sony store still sells it for 1200, and that ain't ok.
