Minix3 - What do/don't you like about it?

Looking for reasons to play around with Minix3. Looked at it a few years ago, back before I had any command-line or system-building savvy. What do you see in Minix3 that is makes it a distinctively interesting or useful OS (as compared to Linux)? I've read the selling points on the homepage, but I'm interested in some outside opinions as well.

Added the poll just for fun.

The following two threads have identical text in the first post.

This last one has identical text to the two above but has a poll attached.

Actually, my first *nix os was Minix v2.
Its man pages are very easy to understand
for me non-english-native-speaker !!
