Yes, it's a very broad question, but some personal anecdotes would be helpful in deciding whether I should invest $200 into just an operating system for my new 2011 27" iMac (with the special 2GB GPU and the upgraded 3.4 i7 processor). So far as I've gathered, I'd be able to play some of my computer games with slightly higher frame rates and be able to play a wider selection. I would also have a very easy time opening .exe and other such files that work just fine in Windows but require a lot of work to open in OS X. But is there anything else that comes with Windows 7? Any input helps. Thanks. Note: I'm a Junior in college if that helps, intent on taking some digital design/media classes while pursuing a career in journalism.
