The cable mess is ugly as hell, but after the New Years break I'll get a bit more time to design and build a better solution for the mess using a local 3d printer and laser cutter.
My hope is that I can modify the device so that it will be possible to just simply plug in any one of the hundreds of new miniPC devices that are being released, it seems, almost daily.
Of course, I'm also avidly waiting for Motorola (or someone) to just make a lapdock that makes my hardware hacking redundant - but I don't predict that this will catch on for another 3 to 4 months, yet. And in the meantime, 5 hour battery life on the Lapdock+MK802 combo that I'm currently running is really nice.
In fact, I'm grandfathering my Macbook Pro as a result of this work, and will turn it into a desktop build server only for the task of running xcodebuild ..
