Sony's sleek digital voice recorder

While cruising around SonyStyle looking for some clue as to whether the NW-A800 might be prepping for a stateside launch, I came across the ICD-U50. What struck me about this device is that it was listed under MP3 players with a 256MB capacity, and I thought "what the...Sony is still selling 256MB MP3 players...and for $99.95!" But then I realized that the ICD-U50 is actually a multifunctional digital voice recorder, and a stylish one at that. I mean, we don't get a lot of standalone voice recorders around here, but I can say with some certainty that this shimmery turquoise model from Sony is a looker in its category. Anyway, if you're in the market for a recorder, check this one out: it comes with headphones, offers MP3 playback, and features a built-in USB plug. Plus, it kind of looks like a race car with a spoiler sticking out of the back. And did I mention it's shiny?
For more than five years, Jasmine France has covered a variety of tech products for CNET--from scanners to keyboards to GPS devices--but she's happiest where she is now: sitting atop a pile of MP3 players, "testing" every music service known to man, and jamming a variety of earbuds in every shape and color into her absurdly small ears. E-mail Jasmine.
