I guess it is all a matter of personal choice. I like newer-"better" things myself, but for those who prefer practicality, XP is still the answer in some cases.
I concur Malmental, it is a bit early for W8. Apparently, MS thinks we all needs an OS with the looks of the WP7 OS. I'm not too crazy about what I've seen thus far, but if MS does a public beta program again, I'll definitely give it a try/chance.
