I remember when I wanted to make a portal 2 mod that would've changed the way portal 2 was played and would've gotten us both hired but then you told me you didn't know C++ yet :C
False. But I typically give a windows 3-6 months before even trying it, just for major bugs to get knocked out, or in the case of vista to avoid it completely.
It is absolutely terrible if you can't function without the start button on the bottom left, otherwise from what I've seen it functions fine. And uses less RAM.
