amok: Honestly though, I am now on Win 7 - is it really worth it to upgrade to Win 8? do I really gain anything (except a new look)?
Well, my PC died the day after I upgraded.So I really hadn't got the time to put it through its paces, but I did like it. The opinions are somewhat controversial. The way I configured the Metro surface it increased the efficiency greatly. Apart from that, the task manager made a giant leap and it simply runs faster and slicker.
It is probably the "least necessary upgrade" in any windows. (Except of course XP -> Vista, which as crap). No big leaps, but many small improvements. I expect it to become really good once the appstore takes off, as there is a lot of potential.
