I think that you would be "forced" to run the Metro-style Start Screen, or stay with Win7. The Metro-style Start Screen contributes absolutely nothing to the computing experience. But it is really essential for Microsoft.
Microsoft wants to condition users to the Metro Interface. Some clever marketer in Microsoft has decided that this is the best way to steer users to Microsoft smartphones and tablets. Without conditioning the users at the desktop, there is no desire by the average user to "go Metro". Personally, I find Metro unattractive and rather "retro". It reminds me of front ends circa 1980's.
Microsoft also wants to make money from its app store, just announced. So, without the Start Screen, there is no money coming from the app store!!! It is as simple as that.
As from my above post, I think you are quite wrong. You make it sound like this evolution started here. In XP, we are were given the ability to put apps in the task bar as well as the Start Bar, this evolved in Vista and Further in 7. Giving more room for "priority apps" isn't a new thing, one that Microsoft has been doing there homework on and realizing how much people use. Windows 8 just gives is a more organized way to get to those apps quicker.
Thus, the Start Screen is (a) a Marketing Device and (b) a Money-making proposition. Because Microsoft wants to have the opportunity of selling these $1.99 - $4.99 apps to tens of millions of users, it has gone ahead and deleted access to hundreds (or even thousands) of desktop gadgets (that were doing much of the same thing and did not cost a penny).
I will say for the first time, I do agree with you. This is another way for them to make money, but you are taking it quite too far. They are forcing us just as much to buy apps as they have done to buy Office! It will be up to you, you want a cooler weather app .... your choice to but it.
I am still trying to figure out why you are even on this forum, if you hate the operating system so much. Not looking for a fight, just never understand haters on a forum ......
