well ofcourse the nano supports playlists. you can even create playlists on the iPod. I don't see a reason why the iRiver 700 series wouldn't support playlists, although i imagine you would either have to create them with WMP, or create them yourself. (try opening any playlists with notepad, and you'll see what i mean.) the nano, again is probablly tied to iTunes unless you use a 3rd party app. in iTunes you can easily create playlists and then drag and drop. enjoy. i have an iPod mini and it rocks!
