Drawback is license bettter to say history of license and not so crowded community but it can use lots of NetBSD packages so it's not so "unmaintained". But Minix provides possible future alternative to Linux. Also currently drawback (among others) in Minix is lack of something like cgroups feature in Linux kernel.
