Just got it at Best Buy (Novi, MI). They had four and their existence was news to them. They were on a pegboard near portable radios and accessories. The guy I asked said, "If we were to get anything like that, it'd probably be right around ...well, whaddya know. Here it is." Then he got on his little radio and told everyone else.
Honestly, I would have expected them to be featured on a display near stuff such as the Zune, but lacking an MP3 player, I can understand the logic. They only had four in stock. Three now.
The charger cord that comes with it is a mini to USB cable meant to plug into a computer. Luckily, I have an overabundance of min-USB wall warts. It's plugged into one of those now.
I will test it out in the car. Tomorrow, most likely. If not, I'm sure it'll get put through the paces over the weekend.
No AM isn't a deal-breaker here, as the big sports station is an AM-FM simulcast and the all-news AM station is on a sub of THAT.
Walking the fine line between jaw-dropping and a plain ol' yawn.
