I must admit this is why I kept away, but after playing with one at oshcamp thanks to Omer, I ordered one as I can run FreeBSD on their currently, not fussed about GPU support as im running the pi headless but I was unaware that the GPU is critical to system initialisation & support is mandatory. If I can have a functional userland with a headless pi it means I don't have to have bigger box using lots of electricity for testing/dev.
