Not as many viruses and I know the OS better. I'm willing to drop that requirement because it is a pain the ass to find parts apparently
Update: I'm looking at the Corsair TX850 right now. Is $30 more worth it if your buying a modular power supply?
Windows is just as easy to learn as iOS. You should give it a try.
Also I don't understand why people use the logic of "not a lot of viruses." I mean that factor doesn't matter, because there are many free/paid anti-viruses out there that are outstanding in terms of performance. Also just because the virus amount is few, doesn't mean they are any less dangerous. The damage they create doesn't shrink, they can be as equally painful as Windows viruses.
