Note that there is quite a big difference in goals between the MINIX versions that were current when Linus started writing Linux (i.e. MINIX 2.0 and earlier) and the MINIX3 project. For early versions of MINIX the goal was teaching. Many limitations were left in place, both to keep the system simple and leave space for assignments for undergraduate students. Many people in the MINIX community went to the Linux community because Andy Tanenbaum would usualy reject patches and Linus would welcome them. Way later the MINIX3 project was created as research project. It has many cool ideas.
