I also have one (#27, I believe), and love it. I don't want something that racks with the rest of my equipment, as I already have two 5' racks full of equipment in my living room, and don't have room for more. The SliMP3 sits on my tv (56" 16:9 HD set), next to my center speaker. It also sits snugly in front of the Linksys WAP11 802.11b access point that I use to bridge my living room ethernet devices to my spare bedroom/home office LAN.

As for the high voltage on the exposed board, there isn't any. The power supply is feeding 5V at a low amperage. Besides, once the unit is plugged in, you'd never need to touch it, unless you're moving it around. If you're doing that, just unplug it.

I agree it's about $100 more than it should be, but until Sean can ramp up production, the low volume is increasing component costs.

Plus, the server code's written entirely in Perl. Infinite hackability (I added Live365 streaming capability to mine.)
