Adding to that, his stated advantage of not having to limit yourself to one platform also seems opposite of my experience (i.e. keeping all on the same platform is an advantage).
When you have a big system with disjoint parts written in different languages, re-use and refactoring is a pain, and redundancy is almost certain to creep in (and with redundancy often comes inconsistency).
