In many of my remote-monitoring/control applications, the BBG is nearly ideal for the power profile, I/O capability, and form factor. I'm not using it as a desktop workstation. I also appreciate that the processor isn't just a re-purposed GPU/CPU combo originally designed for a cell phone, with a binary blob controlling the GPU and then FBSD being loaded and executed by the CPU. This information may be outdated, but that was my understanding of the Pi processor architecture. I'm unable to parse some of your other comments, but I will say that I've used 802.11b/g/a/n dongles (Wifi) on the BBG without too many issues. As for SDIO, that is (unfortunately) a closed spec, but there has been a lot of useful reverse-engineering that allows many SDIO peripherals to work fine (perhaps not under FBSD -- however). --- Zach
