The OP did mention that he wanted a primarily music player so I recommended getting something like a Cowon, with JetAudio/BBE support, the ability to play virtually any format, drag and drop transfer, and a great Wolfson DAC to boot (to me it's not just about the DAC, though to be honest Wolfson's are overrated anyway). I love my 4G Touch and 3GS as much as the next guy, but as
purely music players they leave a lot to be desired. Most discussions re: smartphones as music players seem to revolve around the DAC, as if it's the be all and end all of everything and then degenerate into responses parotting the masses about some great Wolfson chip in this or that phone.
But hey, if the OP wants an all-in-one phone more power to him.
No one's going to force him into buying a cheap Nokia. Then again the DAC in that N97 I used to have was pretty good too. But that wasn't exactly cheap.
