Well, as you yourself pointed out it means one can use the HDMI output of the BBB and wired Ethernet. This board was designed with the BBB in mind, I was aware of the other BB variants (including the Enhanced) when i designed it.
For example, in the case of the 3d printer use, the Black may be a better option than the Green. It is for me, because it does have a HDMI output and that lets me have a local display easily attached to the printer. For example : http://www.thing-printer.com/product/manga-screen/ and wired ethernet. As far as USB implementation goes, I just checked the BBG USB Schematics and make the following observations. The 4 port USB hub of the BBG all share the same USB power output, and are limited to 1.7A total (0.425 per port equal share). A short or power fault on any USB port will render the other USB ports of the BBG inoperable. My hub has independent 500ma power control for each port (2A total) And, yes this costs more, but is more robust and is a more compliant solution. A fault on any one port is isolated from the other ports and can be reported upstream to the BBB. It all depends on your use case, which is the main reason I made this announcement to determine if there was enough interest in this board to explore producing it in volume for wider accessibility then just for me and a couple of people I know. >From the replies I have read so far, I am guessing there probably is, and so I am now doing the work to plan a production run and squeeze the production cost as much as possible so that its economic to produce.
