I have my doubts M$ was really that keen on that path; after all, there's a lot of stuff in Xenix that M$ wouldn't own and that's always been a problem for Gates and the boys. So OS/2 for a while was the heir apparent, which would have also changed things quite a bit (for good, I think, but many disagree). What we got was stepchild of VMS, which also could have been great, but has wandered off in it's own direction.
