Enough with this BS made up crap for reasons to justify not wanting Windows 8. All theses complaints about "closing" the system are completely invalid. It is only adding another method of acquiring content, in a more secure and controlled manner. NOTHING is being closed down!
You cannot install unsigned apps on RT/ARM for starters, this is not a made up thing, it is a reality. Forget that for a second, the microsoft store will not take submissions unless they are signed and certified. Non-WinRT apps can only be submitted in the form of a website link and will be only legacy supported going forward. If you don't think that non-WinRT apps are going to be as deprecated as possible then you aren't even trying, there is a reason Metro is the locked in startup option without even a toggle to disable.
To act like this is no big deal and call people paranoid when even Microsoft itself labels Windows 8 one of their biggest gambles ever is really dishonest. Many companies feel that closed software platforms at the future and Microsoft is increasingly taking such a stance. Windows 8 is the first step in that direction and that's why people are frustrated. Most people would be happy with Windows 8 if Microsoft would preserve user choice and options instead of continually extinguishing it to play catch up with Apple and Google.
It's not just about disliking Metro, it's a complicated issue. Development resources are going to go where the eyeballs are and if Metro/RT are the defacto standard by forced adoption then it will move in that direction. Corporate legacy will only hold up that process for so long. I agree that a walled garden is fine for the average user but if it means that one day I have to jailbreak my own operating system then I'm going to bitch on the internet about it whether you like it or not.
