I was going to use a RasPi, but I/O was too slow as it had to shove both the Ethernet and Disk through the same USB controller.
The other thing I'm using these things for (at least the RasPis) is a temporary fix for when someone's computer is busted -- it gets them back online with access to most of their daily routine, while I'm taking time to repair the PC. The BBB might have a bit more performance, so I might add that to the mix too.
The power consumption is stupidly low, the colo company had to find a different meter to measure it from their normal server oriented one.
I use it as a DNS server, and SSH tunnel destination.
They gave me an IP address, subnet mask, and gateway, I preconfigured it, and posted them the board in a cheap case, plus the power supply with plug.
They invoice me annually for the power used including an amount of bandwidth which I never come near.
This is the PSU I use:

But, I think it just takes one small project to get you started. I've noticed that this has a snowball effect as I start reading more and talking to more people about electronics and automation. Lots of fun! It's all about hacking, learning and having a good time!
Mine is currently a part time camera host for the (hot, young) chick cam, and rapidly getting the electronics and control programming to run the door on the coop. My long term plan is to have a few webcams in the coop and do some computer vision for chicken detection.
Pulling in the Shenzhen thread -- I wish I had the lab I had in HS 20 years back to do this: a bench full of scopes and power supplies, meters, and a parts room that was open for use. No paying retail + $10 shipping and waiting a week for parts.
I've finally got the last few parts to move it from breadboard to soldered pc board, so I'm hoping to get that done this weekend.
And the nerd/hacker/enthusiast in me would gladly put down the cash to make it happen.
However, I also run into a wall when thinking of what to do with such a device. I'm not inspired by webcam+embedded linux. I don't want home automation. I already have devices hooked up to a TV. I work on the Kindles, which use Android (Fire) and embedded Linux (eink), so I can't argue buying a BeagleBoard for educational reasons.
Every time a product like this comes up, I get excited and start searching the TI website or BeagleBoard.org or Raspberry Pi or Arduino for lists of related components I could purchase to put together. Make my own weather station? I live in Seattle, the weather never changes :). What about a toiler paper roll sensor so I know if I need to buy more next time I'm at costco? (with a gf, this is hard problem!). I don't want this electronic staying in the bathroom around the moisture. What about getting a blue light star tracker and calculating celestial position like the old stealth fighters did? Cool, but kind of niche.
The closest idea I came up with is making an RC car. It would get me into the shop to make a frame, perhaps use a 3D printer for mold coverings, and be a fun demo with friends. When I start looking for motors, I get stuck finding a place to buy a motor. Take this page, for example:
http://www.ti.com/tool/dk-lm4f-drv8312
It's unclear to me if this page is a 'kit' for a large shop who want to try out this motor for a specific application. Or do I really need the huge controller board to operate this brushless motor?
Also, is it even possible to buy 4 or 8 of the motors? Or do I really need to put in an order of 1k or 10k units?!?!
Forgive the naive question, but where do other people go shopping for related components like a motor to wire together with these kits? What am I doing wrong?
