It’s not ignorant. I have a couple Valid points. I have Vista and have used it plenty. It’s not so much the performance, it’s that Windows has a crapper load of processes that need my administration access o.k.'d. Now this would seem like a good thing rather than a flaw but I have encountered several tasks that won’t let me do what I want even WITH administrative rights that I set up for myself. I once had to do some crazy Command Prompt stuff just to get a video game to run properly.
Also, Windows has to consume an EXTRA gig of ram just to run properly in dual boot. I generally want to keep all the ram I can when working with 3D applications, especially with particles and fluids, since your scene is stored in ram upon the loading of your file.
The main point, though, is that I don’t want to deal with viruses. Sounds stupid, but when you life and lively hood are dependent on a small box inside your computer, you’d generally want to protect that as much as possible. I know people that get viruses with Norton installed and properly updated. Not good.
Maybe faster but not a better experience. OS X as an operating system is much less frustrating than Windows and I’d rival your comment with benchmark tests because of the ram issue. I also do a lot of other work on the OS X only side and I need to reserve as much hard drive space as possible. But I never know how much I’ll actually need yet Windows has to have a dedicated amount, especially if I’m rendering.
Don’t tell someone they are ignorant because of a preference. I respect your opinion but disagree. Good day to you sir
