No need to 'defend these decisions', you like it or don't, maybe somewhere in between.
It's your choice to run it or not, there are alternatives.
Right now I am in between, and am hanging in to see where it all leads. I picked up the OS upgrade for only 40 bucks so if I decide to go backwords eventually, I am not out that much. The addition of the start menu and the app store make the os more interesting, I will say that. My work laptops still run 7, and I don't see that changing any time soon. I wish desktop users like myself, who still comprise a massive chunk of windows users over all, did not have to feel like 2nd class citizens with the release of this OS. For instance, I would love to see some apps in the app store that are designed with desktop users in mind, rather than the touch first stuff. Hey, maybe they can even state, 'desktop only', or create a brand new category in the app store. Small things like this can go a long way to helping us desktop users feel a little less left out.. How hard can it be to make the os and the app store slightly more chameleon like, with all the same underlying code, so that desktop users still feel like we are using an os that is designed with us in mind, instead of feeling like we are just after thoughts..
I do tend to post thoughts like these every few weeks or so, and I continue to use windows 8. I believe that there are a lot of Microsoft employees within the boards, and that they comprise a fair margin of those who are out there in these boards defending the OS. Many of my posts have been aimed at them. There have been some rock solid suggestions made by yours truly on how to make this os into a winner..
When I have time, I intend to reload my downstairs machine and hopefully resolve the sharing issue...
