I think the only thing Windows 8 has going for it is it's fast bootup time. But by the time Windows 8 is released and hardware manufacturers add crapware onto Windows 8, the whole system will feel buggy and slow. Just like with windows 7 crapware preinstalled.
While pre-installed bloatware is to be expected I don't see how that is in any way relevant to the OS itself and its features? It's not an argument for or against; in fact it's not an argument at all, at least not based in any logic.

A clean reinstall is but a few clicks away. I think that's what most people go by anyway.
