I got my s:flo2 on Feburary and I'm very happy how it sounds . After using it for 1 month , I'm really frustrated with its UI, quite sluggish, perhaps I already get used to Desire HD UI. Finally I went back to Desire HD for music listening , but it drains a lot of battery !
So I need another portable source gear
-a more responsive UI
-able to play flac , mp3 , wma,ape
-superb batter life
I found cowon J3 is exactly what I need. How you guys think ? J3 is a good choice ?
