Well...
@Kenny Millar:
"When I saw it's user interface and features, I said to myself why were Nokia, Sony, Motorola not doing this 10 years ago?"
Because there was no such thing as an "mp3" format 10 years ago! And cellphones were, well, cellphones. Even stuff like "digital cellphones", "SMS" and even "Caller ID" were either premiums or nonexistant. Back then I was using my Ericsson, which had 4 "ringtones": Low, Med, High, Mixed. The most high-tech phone I remember back then might be the StarTAC. Flash cards were 20 *megabyte* on the high-end. When were you born? The whole mp3 revolution started somewhere around mid-1998: I remember it clearly because it was when I also got my first laptop (well, my own laptop, that is) and found a use for the 3Gb HD bestowed on my Fujitsu Lifebook.
Fast forward to now, I am happy with my W300i (damn I look like a SE walking commercial!) which has an iPod-ish interface (on the music selection, that is; now that was true innovation on the iPod), I can dump lots of mp3 on it by using it as if it were a Flash drive, no weird software required. IIRC, Windows Media Player has some nifty "sync" feature that basically does the same that iTunes does, but with *any* removable device. (just don't use the transcoder, it changes everything to wma!)
Oh, and well, I've noticed lately that there are a hell of a lot SonyEriccson's out there, it looks like the W series has sucsessfully revived the Walkman brand. My own W300 seems to be as common as the old Nokia 5120, back in the day...
