Re: To be honest...
What effort? Moving to Linux was as simple as installing it on a spare partition on my BSD/Coherent/Minix test box and rebooting. True, I had to recompile a few things. And I had to re-write a few scripts (both the Coherent and Minix versions of the various shells had oddities/errata/bugs if you came to them from BSD). But Linux was obviously a un*x right from the git-go. Took no effort at all. Certainly a lot less than moving from XP to Vista or Win7 to Win8 or Win8 to Win10 ...
When I opted out of the Redmond clusterfuck, it was only as a support person. I had been using un*x as my primary OS longer than Microsoft had been selling an OS.
