Can't agree enough. I commented at the time that no good would come of having three different (and non-compatible) products called Windows 8 and sharing the same interface. An interface that was an OK idea on touch devices, but was stunningly un-suited to a traditional keyboard/mouse setup. The most stupid thing is that as soon as the public saw/used Windows 8 on a PC in test/beta they said it was shit and Microsoft decided they were all wrong and continued as planned.
Windows 8 x86/x64 != Windows 8 RT != Windows Mobile 8 (or whatever it was called)
