Read so many threads, decided to go for a Cowon J3 (even though it felt a bit expensive), realized you can only get it second-hand now, and now I am bit confused about which PMP to get. My price range is something like €100/$130 -- €230/$300. I will use to play music, that's about it.
In terms of priorities I'd say:
1(most important). audio quality for a wide range of stuff (rock, jazz, classical); loseless support (FLAC mostly)
2. decent battery life. (using one of: Grado SR60; Sennheiser HD229, Superlux HD668B)
3. good storage (32go+32go would be very good, 16go+32go is good already), not sure how I feel about bigger non-flash storage (like the X7 has)
4. ready and easy to use: I know I will not want to walk around with an extra amp (but maybe it is worth the extra bulk?); and if the native interface is intuitive enough, that's nice too.
5. an acceptable screen: so you can easily choose music while walking around and see the art.
6(optional). not overly bulky and heavy
Right now I mostly using an iPod Nano (4thG) or an iPhone 4, but I need the battery and storage of the iPhone for other stuff, and (my/that) Nano has a few drawbacks (iTunes, battery, sound quality, limited storage).
I am curious about trying a Cowon, but I am open to any suggestion (really).
