Besides the drawback of using mirosd, the bigger problem is that
binary blob driver for the gpu. Broadcom is subsidising sales to
Raspberrypi foundation. If an open driver is not available, the life
of this one will be 6 months. It has been the case with every piece of
hardware having a closed driver.
One is totally at the mercy of broadcom for driver updates and should
they not make sufficient money on the SOC, they will simply not
release a new driver version to keep pace with kernel and opengl
But given the low price, it is one neat peice of hardware to muck
about with even for 6 months.
It will also screw Samsung, TI, Wondermedia, and a host of other vendors badly.
