Many people here aren't liking the changes in Windows 8, as I gather, is because...
1) They have years of habit and experience of using the pre-Win8 interface, and the changes are dramatic enough to break the routine/muscle memory while not offering anything that significantly improves the productivity (or even reduces it).
2) They use the PC for more than just web browsing and emailing (which is understandably not an accurate representation of the general public since this is Slashdot). It's much less rare for people here to operate on multiple monitors and have a few windows opening at the same time. To them, this Metro and Start Screen thing is counter-productive.
But the point is, they're forced to adapt (if they upgrade to Win8). To adopt a car analogy, it's like the maker decides to utilize a control stick for the latest generation instead of the steering wheel - it works, but is less efficient for people used to drive with a steering wheel.
So they'd just stick with the existing car (XP or 7) instead.
But (again), how long can they hold out...? What if this change will remain for Win9/10/11...?
One of the important points is, would businesses in general adopt Windows 8...? I guess we all agree that is unlikely, at least in a short time frame, say 2-3 years, for various reasons. In the meantime, would Microsoft be able to improve and help us have a smoother transition with perhaps Windows 9...? Or would it relent and offer a dual interface in the next version...?
One thing that we sometimes fail to realize, is that computers started as a niche device which are utilized by scientists, engineers and such. Now, computers has become a diverse field which includes desktop, laptops, tablets, smartphones, just to name a few, and are utilized by 3-year old and grandmoms, so we need different interfaces.
The point is, the change in Windows 8 is like... If you force the Chinese and Japanese to use spoons and forks to eat rice and sushis, they can do it, but it's inefficient, and they're not gonna like it.
Another issue is that, if people are to adopt a different interface anyway, why should they adopt Metro...? Why not iOS...? Android...? Chrome OS...? But that's a topic for another day I guess.
Just some random ramblings.
