You seem to have this oh-so-cute vision of Microsoft, as though they're infallible and incapable of making mistakes. You seem to also confuse concepts very easily. For instance, you keep saying "Microsoft isn't stupid". True enough, because Microsoft is a large corporation, and therefore cannot be classified as "stupid". However, those working WITHIN that large corporation certainly ARE stupid, especially if they believe that Windows 8 (in its current form) will in any way be some kind of success story.
Microsoft isn't stupid, but some of its employees (both past and present) have a clear history of making horrendous business decisions. Your constant reference to dinosaurs only shows one thing -- that you're young and ignorant, and have no idea how the world works. You think that just because YOU like the new interface and aren't bothered by it, then nobody else should have any reason to complain either, right? Yeah...Microsoft isn't stupid, but people are.
If you want to keep banging the "Microsoft isn't stupid" drum, go ahead and tell it to brilliant minds responsible for bringing us Windows Millennium edition and Windows Vista. I realize that in all likelihood, you were still crapping in diapers when Windows Me was released, but rest assured, it was an epic failure, requiring XP to make up for the mess. In the same way, Vista was an equally-epic failure, requiring Windows 7 to make up for it.
Take comfort in the fact that Windows 8 WILL, in fact, be an epic failure, requiring Windows 9 to fix it.
