Just to piggy back on this thread, I'm also looking for a relatively simple player for my car. I've long been a fan of the Sansa line, but they've seemingly decided to make their latest models worse in every conceivable way from their older ones.
Here's what I look for in a player:
1 - ability to easily load playlists from a computer (using Mediamonkey, but any PLS/M3U support should be covered in this)
2 - ability to resume podcasts
3 - more than 4 GB of storage space
4 - optionally, a speed control for podcasts
This doesn't seem like too much to ask, but so many reviews of DAPs ignore every one of those items, except for storage. I apparently do not represent a large demographic, but I used to! :-)
