But at the end I didn't understand because he wrote "In the end, 3 days later I had been issued a replacement MacBook Pro which I got just as Mountain Lion released." So he went back right?
The article is about him realizing that his workstation shouldn't run a dead Solaris installation anymore, and more general that he doesn't need to replicate a server on his (workstation) desktop.
A broken laptop (running OS X, not that it is relevant for the meat of the article) just lead to the switch, which wasn't reverted for all we can tell.
Yeah, the laptop (with OS X, incidently) was replaced.
I don't much care either way - I use OSX on my workstations and Ubuntu on my servers - but the title seems overhyped for such a simple article.
