my friend let me borrow the mptrip player. overall, it's pretty good. there are a few downsides though:
- it doesn't include a reverse skip. you can go to the next track, but not backwards.
- the 50 sec anti skip really applies to the mp3 songs only (at least from my friend's and my experience)
- the case looks/is very cheap...it's flimsy and shoddy - but it works so it's basically only a cosmetic concern
- there's an LCD that'll tell you what track you're on...but it won't be able to display the ID3 tag info (title, artist, bitrate, etc)
if you don't mind the lack of the reverse skip (or whatever you call it), this player would suit you well.
