I really wish I knew why mine freezes. Reeeallly wish it made sense, but apparently others have reported the same freezing issues. So I'm not alone, even if it's not happening to everyone. I actually would have stopped using the DX50 and went back to using my smart phone if it weren't the fact that I'm spoiled now with the 256 volume steps, compared to my phones 8 volume steps. Can never find the perfect volume with my phone... lol.
Thus why I am interested in trying out Fiio, mostly the x5 when it is released to compare to the DX50 directly. If I like the Fiio more, I'll get rid of the DX50. Hopefully something is more stable. My phone has no difficulty with my music collection. With the OS all being Android I was actually expecting something a bit more stable.
Fortunately for me, I was never spoiled by the Apple iPod UI because I personally hated it. I hated my iPod. Was a piece of trash as far as I was concerned. Was by far my least favorite portable audio player I ever had, it got replaced while it was still working fine out of pure hate for it. Ever since I have despised Apple products. I have a grudge towards them, and they certainly burned some bridges with me. :p
