Not that I can particularly recall, no. Most folks still use windows (and MS Office) largely because it's still the only real option on the market, not because of any particular other affection for the platform (barring familiarity and ubiquitousness, anyway). Mind you, there is a bit of a comparative aesthetic appreciation for some of the older, simpler, windows systems compared to the newer stuff (mac or windows, really), but that's about the closest I've personally noticed notable inclination towards.
... also, @Ree, if you think apple has done jack-all to prevent MS trapping people into their proprietary software, you really haven't paid any attention to education programs or corporate software use. They don't exactly have great swaths of the state's introductory computer courses being learning to use... whatever it is macs use for office software, I don't even bloody know. Similarly, if they even offer certification in whatever the hell apple's office equivalent is I've never actually heard of it.
There is no alternative office software worth mention (and I say this as someone that actually uses libreoffice for home use). Knowing your way around mac systems will help you in what amounts to an incredibly small subset of industries. I guess it may be marginally better than it was a decade or two ago, but there's no laughing at MS's entirely effective success in trapping people into using their software. They're still incredibly good at that.
