I bought a BBB about 3 weeks ago. Was impressed enough that I bought two more. I have a few Rpis is use around the house as well so I have a little experience with SBCs Anyway. all three BBB has been flawless. No problems at all.
I did discover one thing. Of all the Linux distros out there, I like Ubuntu the best. I found that Ubuntu does not suffer as badly from creeping featurism or from a lack of essential packages. I tried Angstrom first. It got flushed. Then I tried Arch and Debian. Didn’t like Arch at all. Debian was tolerable. Lastly I tried Ubuntu. Ubuntu seems to be the easiest to get configured and running. I was porting code in under an hour. I don’t use a GUI so Ubuntu might not be for everyone.
The really nice part about the BBB is the fact that it boots without a SD card. That leaves the SD card slot available for extra file storage. SInce I do some software development as well as create various appliance-like things, the added hot-plugable storage is wonderful.
The only thing I wish for is the ability to change I2C bus speeds on the fly.
All in all, I am very happy with the BBB.
