Query: great!

I'd have preferred to be able to give 4.75 stars rather than 4 or 5. The reason for this is the placement of the RECORD button. I have made more than a couple inadvertant recordings simply as a result of handling the unit. Other than that, I like the fit and feel of the thing. I don't know that the micro-SD slot contributes much to the user -I think it was meant rather to contribute to SanDisk (manufacturers of same, not coincidentally). I like that the unit will "keep track" of your progress through a long track (I like to use my Sansa for listening to audiobooks, the files of which can be quite long and finding one's place manually can be a rank tedium). The screen is quite nice- disproportionately large for so small a unit. Finally: battery life for mine on the first two charges was between 20 and 22 hours. Not bad at all.
