So, I picked one of these up today and I have to say, I'm impressed.
The built quality is excellent, similar feeling hard plastic (like a Nintendo DS Lite) and virtually weightless.
It is just a basic drag and drop file structure, much the same as a USB memory pen.
Foldering your music on this is a good idea, since the slider button has the function to skip to the next folder, repeat or shuffle all that is on the player.
The sound quality is amazing for something so small and cheap.
The stock headphones are great, but using my Shure e3c's....wow, I nearly deafened myself, so much louder than my Creative Vision:M.
This is totally user friendly, really sleek looking and feeling, and the sound quality has to be heard to be believed (and that's mp3's encoded at 128kb!!!)
I think Apple are going to lose a LOT of potential shuffle customers to this nifty bit of kit.
I recommend getting the most up to date firmware for it too, as the battery indicator doesn't function 100% out of the box, it doesn't impede the playing, but at least you'll know when it needs a charge.
A wall charger would have been nice, but that would've probably bumped the price up more.
All in all, a great, cheap player and a total ipod killer...as all Creative players are =]
