Because they already had a years stable developed core... I mean it's a good option.

In any case only the core (kernel) is used... the UI, drivers, etc are all developed by Sony.

Sony sucks at software if that wasn't apparant. XMB is a great simple OS for TV's, but once on PSP and PS3, it got too crowded, slow, and irrititating.

XMD is BSD based.

I guess it is a similar case to the smartphones right now. They use android because it is free and good; and there are already plenty of tools for it. So this OS is free; for what they are doing is good; and as it has more time in the developer space, it has more tools for it.

I really dont know if the OS is good or not, since I have only used in my life Windows, MacOS, and tried android in some phone.

MacOSX is based on freeBSD, if recall correctly.

It is

Based in BSD... freeBSD is a distribution.

And AMD have drives to Mac OS X... I don't why people thinks there are no driver for freeBSD... BTW the driver for a console is way different with direct access to GPU without concurrence with OS.

How much do consoles gain in performance thanks to no overhead?

It's way relation to make this comparison... Camark said one time that with consoles without all PC overhead runs games in the same hardware with twice performance.

But here we are talking only about driver overhead that I guess it's the small overhead to be compared.

But if the BSD is free, shouldnt MacOS be free too (similar to android and linux)? The last time I checked apple website; you needed to pay for the OS update.
