Stumbled upon this article. Wise words of caution. 
Very amusing satire. However, it is worthwhile to point out that even though RasPi Model A/B is "the size of a credit card" it won't fit in an Altoids box because it doesn't have rounded corners like a credit card. The BeagleBone does. Gerald Coley told me those rounded corners and mounting holes made BeagleBone placement and routing a real pain.
I might have to try one of these beaglebone devices.
Mine arrived as well. I was stupid and didn't order the power supply, or at least the pigtail, that 2.5 mm connector was hard to find. Believe it or not Radio Shack saved the day as I was able to buy one of their Adaptaplug (size A) plugs along with the socket and I was able to create a 5v ps to get me going, albeit at only 850 mA.
The image i downloaded from their site was a typical installation, dd the image onto the SD card. Plugged it in and it booted right up. Showed up on my network as odroid, I ssh'd in and was good to go.
It's a bit early, but I think this is my favorite board yet :-)

BTW, some of the reasons I say I like this board are:
1) Quad core
2) Modern Ubuntu OS 14.04
3) Great accessory support - their site has a bunch of stuff I'd like to purchase, and it is inexpensive
The form factor is dang close to that of the Pi. And it was still only ~$35.
So far, I like it. I may blog about it myself. I've got to finish up my B+ STEM blogs I promised Dave I would do first though. I'm working on them right now.

If you ever need to put it in a project case then shout up !!!
I think in many local stores then regular customers could indeed be mentioned on 1 hand
