What I particularly like about how the Minix book is written (at least the 2nd edition copy I have) is how he goes over various sophisticated options for disc reading, scheduling, resource locks, and then says 'now, are you really going to need this for an OS running on a PC? No.' He then implements a solution which is only as complex as needed. It's refreshing going to it from other textbooks like say, the Dragon Book, which seem to pull the reader towards the path of greater complexity.
