With the exception that the Beagle is Open Source for software and hardware and has an edge over the Raspberry with the dual PRU units. Production is high enough that they might just stay around for some time. I have two. I also have a Replicape which has the drivers and sensor conditioning to run a 3D printer. Now granted size 17 motors aren't really adequate for a big mill or lathe. But as a model for an interface card to run LinuxCNC it's ideal. Problem is that the designer of the Replicape built 500 of the current version for the 3D printing market. I'd suspect during the time it takes him to sell all 500, an equivalent cape for LinuxCNC and machine control would sell 5. So if the BBB vanished with sales so low who in their right mind would build 500 BBB clones and 500 MachineKit Capes. They might build a dedicated 3D printer wth Beagle and Replicape all on one board. But then I'm probably what Jim Craig described as one of the "ignorant and misinformed half-hearted programmers" that doesn't like Linux all that much. And Jim's comments outline perfectly why the Linux Community is so self congratulating and why MACH3 and now other CNC programs are still the _go_to_ choice. Just look at Apple, Microsoft and now Android/Google. My suggestion is: Create a Linux Installation CD where everything and I do mean everything for configuration, tweaking, and compiling applications is only done with windowed interfaces so a user never ever in 10 years of use has to use a command line. Then you will have a Linux System that will be adopted by the masses. The measure of how well that is done can be measured by not being able to run anything from the command line because the only response from the command line execution would be "Cannot Run From Command Line". It's a philosophical difference. Won't happen in Linux other than in the Google/Android Model. I've even run Android OS on my BeagleBone Black with the touch screen. It's clumsy but it works but then I use an iPhone so it's probably just a lack of knowledge on the Android.
