I fucking hate it.
Seriously, I think it's the worst design decision Microsoft has ever made. Yes, it makes things marginally more readable. Okay, if I was on a tablet, I might appreciate it. I'm not on a tablet. Stop shoving this shit down my throat. (Okay, bit of an overreaction there, I could just -not upgrade-
)
Besides that, Windows 8 is all right. I'll admit the app store is a pretty good idea, as it makes getting software about 4x easier. And the performance improvements make it seem pretty streamlined overall. But that's about where the pros end.
As for other cons, the default browser is IE, as usual. This wouldn't be a problem, except I just installed firefox, told it to be my default browser - and shit's still opening in IE. IE has been metrofied, and it has an "app" counterpart, and it seems any app that wants to open a webpage will do it with the default "app" web browser. Since firefox hasn't come out with one yet, I think I'm stuck with IE for that.
Also, to do anything, you have to have a microsoft account. Okay, you can play solitaire. And maybe browse the internet. But 98% of apps require you to be logged in to a microsoft account.
I almost certainly won't be getting this as my main OS on any of my computers. The only reason I have it installed on my laptop is because I was interested in seeing what changes they're making. And obviously, I'm not very happy with them. I'm sticking with Windows 7, which as far as I'm concerned, was the last good Windows OS. Unless they see the error of their ways and go back after 8 flops.
