Tried it, hated it, never again. I mostly use my phone as a music player, and here are all issues that it had, all of which were really annoying to me in daily use
- Every time I connect to charge, my on-the-go playlist is reset
- No custom EQ
- No browse-by-folder
- Only exchange files with one machine, and can't treat it as just a hard drive that happens to have music
- Stupid 'features' enabled by default, such as shake-to-randomize-song-order, I had some 'what the fuck?' moments there before I learned to turn them off.
Now a happy Galaxy Note II user, it's not exactly cheap but none of the above issues, bigger screen, and if I don't like the player that came with it I could always change it. I also think it looks better but that's of course subjective. I'm hardly a tinkerer these days, am hardly exposed to ads (don't watch TV for example, and walk to work so don't see ads in public transport much), and price is pretty much irrelevant for me when choosing phones.
The iPhone is great if you happen to like it just the way Uncle Steve wants it, but I have a hard time understanding how anybody who actually has own opinions of their own could do that.
