Dan, of Dan's data, reviews a couple of miniscule MP3 players - in his usual fairly thorough/rambling manner. Go read it, it's interesting. To cut a long story short, he names "George" the winningest of the two players reviewed, for a number of reasons including usability, battery life, price, and sound quality (I think that's a complete set, actually).
Anyway, if anyone's paying attention out there, I'd like a "George", please :)
