So I obtained a copy of Microsoft Vista Ultimate Edition and decided to install it on my MacBook Pro in Parallels to replace XP. I need Windows to run two specific programs that don't work in OSX. So far, seems to work. Since Aero doesn't function in parallels, I ALSO decided to install it on my MacBook which I haven't really been using much lately (I use it primarily for travel). I used Bootcamp to install it which was a flawless experience. There was no reason for this other then to experience Vista the way PC users experience it from a speed, performance, GUI and everything-else perspective. Since it's installed natively, Aero works great. Vista is pretty quick and snappy. What does suck, however, is the design of the OS. I don't understand why anyone would want to pay such a large sum to upgrade from XP. I understand that it makes sense when upgrading computers, but to just upgrade the OS? Not worth it. I am also surprised by how people are comparing it to OS X and saying that Microsoft copied Apple. Yes, there are some similarities in some of the features and icons. But overall, Microsoft failed in trying to imitate Apple. While the transparency effects are cool, Microsoft didn't refine it enough. For example, the text at the top of a window (name of program name of site you are visiting) has a very amateurish photoshop-like glow. I am also shocked by the security of this thing. When I saw that Mac commercial with the PC bodyguard, I thought it was a bit over the top. But in reality, it's accurate. Every time you download a program, every time you visit a website, every time you do something that you want to do, Vista asks you if you really want to do it. Yes, you can turn that function off, but the point is that it's a pretty ridiculous feature. So, why am I running this natively on one machine? Primarily, it's so that I can legitimately defend OS X as a vastly superior operating system against the naysayers.
