I understand why you're hesitant to try it out and see for yourself, being such a costly program and all.
Oh, you silly kids! What the OSS fanatics fail to understand is that once a person leaves graduate school to get a "real job" in the "real world" that time suddenly becomes much more important to money for many, many people. Saving a few hundred bucks on software is pointless (to me) if I have to spend more than an hour dicking with it, for example. For other people, a few hundred bucks (actually Office 365 is only $100/year) might be worth two hours of their time to dick with. Anything more than that, and it's not worth my time.
