then again, does linux? probably not. Its free which is a massive benefit to the user. Also thinking about it, do we want our community breached by non-computing people? possibly not, as this would make linux support harder. Then again I truely believe in free software and that anyone can be taught to use linux.
I've used ubuntu with OAPs many times, some for the first time they have used a computer - big email, big internet button, that's what they are after. Big benefit once installed, there is none of the crap of M$ / your computer doesn't go slower with time.. etc etc.
I'd also argue that Apple have the media processing down, not microsoft.
