You'd be surprised at how much home-grown stuff we run around here (I'm a grad student at MIT). All of the school-owned computers still run Athena OS, everyone uses Kerberos, emacs still rules the day..I once saw a secretary use the `finger` command to look up a phone number and couldn't believe it. The problem is all the home-grown stuff is inevitably pretty low-level compared to today's solutions. Sure, there are plenty of hackers around to build OSS replacements for all our needs, but these hackers are students and professors: their main job is to do research, not implement enterprise software. So I think the decision to move to outlook was probably based on the simple fact that it offers a lot of nice features that we don't currently have.
