Errr....
You are basing this on one individual's thoughts - just a day after it was released? [Sort of like if one person at a restaurant falls sick, so will everyone else at the restaurant.] Try it yourself. Vista [after the kinks were cleaned up] isn't a bad OS. But some reviewers killed it so badly in reviews that it never took off. Used it for 9 months [inmcluding 5 months after Win 7 came out] before I went to Win 7.
One comment on the boot up time. Unsure if that 8 seconds was on a HDD or a SSD. SSDs dramatically reduce time at boot up. Additionally, Microsoft is sort of cheating by hybernating the kernel on a normal shutdown [i.e. not after security updates, core software changes, etc.].
Personally, i'll start off with the "classic" Windows 7 interface and switch at one point [on my desktop].
