There's one major drawback to these Sansas and like others have mentioned the playlist function is worthless. I don't understand why the people who engineer these don't incorporate utility. The folks of CD players final caught on, make a multi disk CD player. For some reason, the transition to digital was done by a bunch of yahoos who don't know what CDs are, or what an album is (much less an album concept). What the Sansa people need to do is provide a means to play more than one album in a row, like loading a CD player with a bunch of disks. I mean come on isn't that like a basic function of playing music? And making playlists in WMP does NOT work, not if you already have music on the MP3 player. YOu will end up with multiple copies of songs and clog up your player. And unlike what people say, you can not delete files from teh Sansa you have re-format the damn thing. Very amateur unsophisticated piece of crap firmware if you ask me. Unbelievable they can sell so many.Playlists, are a whole other Sandisk Fiasco. This function is total a joke.

Another just exasperating failing of the Sansa is its inability to organize music as it was filed on the computer. Keeping your music organized is hardly just drag and drop. AFter many fruitless hours trying to delete artists that were songs, and songs that were artists or albums that were songs, no rhym or reason, I finally came across this:

http://www.expansys.hu/ft.aspx?k=80153 "Unlike some other mp3 players, the Sansa follows the windows Media Player format, so the album layout within the player does not follow the filename/directory layout. It goes on the information within the file.

Right click on a mp3 song file and select properties. Then Summary-Advanced.
You can edit the songs there manually, putting in Artist Album info...but it would be very slow.
Just run Windows media player 10, press F3 and search for your mp3 files, then right click on an album.
Select Find Album Info. Find all your albums this way, once the album is found the song names/artist/album/genre info will be automatically entered into your mp3 files."

I have to go through all the songs in a particular album on my computer and make sure the artist, album, song title etc are all the same. And even then its still a crap shoot. But I think the biggest failing of the Sansa Engineers and Programmers is not having a way to delete aberrant files without having to wipe out the entire Sansa contents. What another joke. Come on you guys, program some function into these!!

Anyway, I'm kind of pissed off about this Sansa. If You are a fogie like say over 30 (I'm in my 40s) and have like  a virtual ton of CDs, and some record albums you'd like to store on a MP3 Player, you may want to keep shopping. The Sansa aint it.

One last rant, who on earth decided to attach the lanyard to the top of the player, louise, man, should have put it at the bottom, that way when you wear it around your neck its easier to handle and use. 

In fact if Sandisk wants to out sell Apple, hire me as a programmer supervisor, I design, they program, and we will sell sell sell. I am the epitomy of ergonomic and user friendlyness.
