Yeah, I can't see MS deserting AMD/Intel (both of which are not focussed on ARM chips) completely. This is more to allow Windows 8 to run on netbooks, which some say are going to be mostly ARM powered in the future.
Well I believe it runs on a different version of vBulletin (the forum software), which is why the menus etc. look different to those found on VF/SF (EF actually has more in common to other sites which run the same version of vBulletin).
As Windows 8 has not yet been released we can't really help anyone with Windows 8 related issues. This means that it isn't all that fair to rep anyone just because we are here now.
Therefore there is nothing to base badges on - so the admin just give them out if they feel like it.
I have used Firefox ever since getting frustrated with IE6 back in 2004. I have considered switching back to IE - or going to Chrome, however using Firefox now just feels more natural for me than any other browser.
