This semester was my first semester using iWork for school related work and while at first thinking it was gonna be a hassle, it was quite the opposite. FWIW, I really like Pages and Keynote more than Word and Powerpoint, but for some reason, I wasn't really able to handle Numbers like I would Excel. I thought compatiability was going to be an issue since my college is still primarily MS Office (for reasons of having to email professors my essays or saving my work to be worked on school computers in lab), but with being able to convert documents into Word format or presentations into powerpoint format, it made things much easier. And vice versa, I was easily able to open Word/PPT files, while only having trouble opening Excel files.
