It pushed me off of Office completely. I used Office XP as long as I could, then 2007 when I could. I gave up on 2013 completely - it's just not worth using a proprietary program that clearly hates its users.
If I need to export to Office I use Google Docs, because Libre is still too frustrating. If I don't need a .doc output, it's Latex for pretty things and Textedit for the rest.
I agree that most of the Office-analogues out there aren't very usable, but I'm surprised at how rarely I need one.
