osx allows any app that can print to save as a .pdf. you do not need pages to do this..
My point was that PDF is compatible with practically any computer, even Amigas have PDF viewers. Hence he could email a PDF and the professor would be able to read it, there's no compatibility problem.
I really don't get the statements being made about people needing Office for compatibility at school. Unless you are emailing your work around for other people to copy, or something. If you are collaborating on a project, then you'll email and IM each other most of the time, and that certainly doesn't require Word. These collaborative projects often have a presentation aspect to them at the end as well, and Keynote pees all over Powerpoint.
For the most part, plain text is all you need to bother with. When you write an essay, then the software used is meaningless, because you can either email a PDF or print it out, as long as it meets the requirements (usually Times New Roman 10pt double spaced) then you can use any software to create it. The content is what matters.
So what to use? Try Pages, if you like it (like I do - it lets me just get documents created, no clutter, it just works) then use it. If you don't (like other people do, because they think it is a word processor and not a document producer) then see what deal your university does on Office.
In a business environment, yes, Office compatibility is often an issue. Getting the hang of Office at university isn't a bad idea either. But I hate Office, I detest Word, it does everything it can to stop me being productive. It isn't a Microsoft thing, I think that Excel is their only good bit of software and if you need a spreadsheet then Office is the thing to go for.
