I think the main issues with Linux have been covered.

But to add an analogy. Most people here can drive cars, but how many could jump in a lorry and drive it?
It's still got a wheel on each corner, the steering wheel and the pedals do the same thing, but could you handle the air brakes, the air handbrake, and all the extra gears? Using the linux fan comments here, it's not that much different, and can be done easily with minimal issues...
