Some companies have more than 20-30 employees. All these "quite cheap" expenses quickly add up. This is money better spent towards getting a better product on the shelves.

Now when you consider that managing unix machines requires much less work to begin with, you can't look at "quite cheap" the same way anymore - it's actually "quite expensive".

Not to mention I often see improved performance of server applications just by switching them to a linux host. Samba 4 is indeed very good news.
