>Dismissing Linux as a hobbiest OS definitely turned out badly.

That actually made me laugh. Not because it's untrue, but because it reminded me of this:

   One of the questions that comes up all the time is: How 
   enthusiastic is our support for UNIX?

   Unix was written on our machines and for our machines 
   many years ago. Today, much of UNIX being done is done on 
   our machines. Ten percent of our VAXs are going for UNIX 
   use. UNIX is a simple language, easy to understand, easy 
   to get started with. It’s great for students, great for 
   somewhat casual users, and it’s great for interchanging 
   programs between different machines. And so, because of 
   its popularity in these markets, we support it. We have 
   good UNIX on VAX and good UNIX on PDP-11s.

   It is our belief, however, that serious professional 
   users will run out of things they can do with UNIX. 
   They’ll want a real system and will end up doing VMS when 
   they get to be serious about programming.

   With UNIX, if you’re looking for something, you can 
   easily and quickly check that small manual and find out 
   that it’s not there. With VMS, no matter what you look 
   for — it’s literally a five-foot shelf of documentation — 
   if you look long enough it’s there. That’s the difference 
   — the beauty of UNIX is it’s simple; and the beauty of 
   VMS is that it’s all there.
