Scoble goes (again) into a non-issue discussion

Again Robert Scoble has started a discussion about whether Apple is better than Windows Vista (link).
Just like the other instances he is trying to compaire apples and oranges.

Apple
Apple is a hardware and software supplier. It produces software (application and a OS) which will only run on hardware produced and sold by Apple.

Microsoft
Microsoft is a hardware and software supplier, but mostly a software supplier. It produces software (applications and OS) which will will run on any hardware, produced and sold by anybody, as long as it is based on the old PC design.

In his new post Robert complained about that his new Dell which gave him a blue screen while booting. I’ve been using Dell, Fujitsu, Asus, Compaq, Tatung and HP machines and I agree that there are qualilty differences between the brands but also between the models within a brand. None is trouble free and every model I have used needed two or three firmware updates in order to solve problems with OS during it’s lifetime.
So I ask Robert; Is a blue screen the problem of Microsoft or the problem of the hardware supplier.
