It prolly dont get more barebones than a Chromebook... but you just open it up... 7 seconds later you'r ready to serf the net... an it just keeps workn grate wit no effort.!!!
Chromebooks are really cool, they take some time to get used to. Interestingly enough Amazons Kindle has awesome progams to run as far as small utility type programs and Prime streaming is a plus and i got it for free from optimum many years ago. Kindle uses...what is it Android OS? I am not really up on smart phones OS's though...ah, i digress. I agree that Chromebook should be added and tbh, i dont even know what they call their OS...what is it chromium? oh also, amazon has the audiobooks and i listen to them often. I love cloud computing and first time i tried WiFi i almost passed out from the sheer awe of it all. WiFi totally amazed me and threw me for a loop.
So yeah, my favorite OS? Well that would be OS X. Yes...Yes, i said it. It has BSD blood line and honestly i could not figure out BSD to install it and my days of command line are OVER since Win three one or specifically WFW. OS X will always be my favorite OS and after that Win 7. I actually think Win 7 and OS X are comparable. Never used Win 8. But i am smart enough to know that the new technology Windows was implementing for the simple fact thaey included touch screen would throw a wrench into the OS formerly know as Win 7...a great OS in its own right.
Linux, i have used often and it is fine...well it is the native OS of servers that serve us pages off this thing we call the WWW.
How about some long forgotten OS's that broke ground for what we see today? Amiga abd BeOs anyone? I used BeOS for awhile and i really dont know what happened there but i think they had the first 64Bit OS.

Really, the best OS runs the programs you want to use so i have no loyalty or am not confined to one OS. I buy all my programs since i support the small programmers and just LOVE the technology of it all. For a gamer Win 7 seems to be a safe bet. The way i look at it is OS X is a luxury Mercedes and Windows is more utilitarian and i can get under the hood and tweak to my hearts content. Thing about Windows that people forget is that it has multitudes of people writing software that can break it so it gets a bad rap and undeservedly so. Then you have that ole chestnut called a registry.
I agree with Shrider, BSD is the cream of the crop back line OS...BUT i like GUI's. so...um, yeah give me a cup of OS X and that would suffice. I'm old school and its funny 'cause i remember telling people...OK, like theres this thing called the internet and its like WOW...and when i would tell my friends they would say "oh, your a weirdo" And today those same peeps have their noses in their smart phones and FB everything. Well no big deal.
