To be honest, I never normally like to go anywhere near Windows 8 bashing threads; I don't personally mind it. However, I feel compelled to point out what happened the last time everyone hated a Microsoft OS: They went back to the drawing board and created Windows 7, the best operating system Microsoft have ever created. If they can keep their fingers on the pulse of what people actually want for Blue, they might have a winner on their hands.
They didnt go back to the drawing board at all :/
Vista was replaced quickly due to it being terribly made, comparable to Windows ME.
Windows 7 was, for the most part a major 'patch' on Vista. Not any sort of rewrite. They simply fixed it and made it what Vista should have been.
I stopped using Windows when Vista came out. I'm sorry but its a dinosaur. It's the only major OS still using a closed kernel and base OS, the likes of Apple keep the core of the OS opensource for a reason - stability and compatibility. Windows is dying a slow death right now and the only way to keep it around is to try things like Metro - personally I feel they failed by keeping the desktop as an option - either go the whole hog or dont bother, people simply close metro and carry on using it as if it was Windows 7, thus negating any point in making apps for metro.
Microsoft always try to do things in the most complex, and poorly planned way as possible, refusing to 'share'. IE is a prime example, still using the terrible Trident rendering engine. Windows still using its NT framework, and relying on thousands of DLL libraries, with a dated registry design.
It's high time they got rid of Balmer, who we all know has zero idea when it comes to innovation, he's a corporate face, with a corporate mind, well past his useful stage. Sure in the 90s with the likes of 95, 98 and 2000 he was great for enterprise stuff, but when it comes to modern computing, he has no idea what people want.
Get some fresh faces in there, restructure the company (as its a very well known fact that nearly all Microsoft projects have failed to reach market due to a very bad atmosphere between departments, thus nobody works together to get anything done), and most importantly, rewrite Windows from the ground up. Look at Apple as an example here (and put to the side any hate/fanboyisms, I'm talking tech here). OS X was a fresh OS, based on NextStep, by making that switch, they created an OS that was highly flexible and has stood them well over the years. Because its Unix based there are a HUGE amount of developers able to contribute to the Darwin core. The fact that it has worked so well across PowerPC, Intel 64bit and ARM is a testament to a good OS foundation.
(Also, I do agree with you about Windows 7 - it was by far the best OS they have created, especially in terms of stability)
