Query: Simple yet effective. No Mac compatibility.

This is a great simple mp3 player. It does what it says and does it pretty well. However, it is not seen as a hot pluggable flash drive and requires Samsung's proprietary software.As such, it does not work on the Mac or Linux. In order to use it, I have to fire up my PC, copy mp3's from my Mac to my PC, and then to the Yepp. Samsung has also recently dropped support for their printers on Mac, too. Sad, because they make some great products.
