Just checked my MSDN Academic Alliance account with my college (which I expected to lose but haven't after graduating and am not attending anymore...bonus for me I guess), and saw that they had Win 8 Pro available for download. So, I'm downloading it at the very least so that I'll have it on hand if and when the time comes that it is logical to upgrade to it. My question here is as the title states. Is it too early to do so? Much like launch-day devices that have problems, I don't expect any less from software of this magnitude. But, sometimes the product just happens to have a smooth launch (even though I know this OS had been leaked earlier), and everything works as it should. What I am looking for is compatibility with programs designed (or worked well) with Win 7 Pro on Win 8 Pro. I know it has only been available to certain groups for the past couple of weeks, but has anyone with it had any problems to a point that they needed to revert back to Win 7? No, I'm not talking about petty stuff like the Metro UI, or some "historical pattern" that somehow predicts that the OS is bad without proof. I'd like some actual solid information on major issues if possible, like buggy drivers for things like video cards (Nvidia, for example) and such. Can't very well play games if the video card and the OS don't cooperate, can we?
