Many, many, MANY moons ago - even before 99% of our world even KNEW there was an internet at all, there was a marvelously reliable OS which made the leap very well from DOS to a GUI based format.
I was one of the very few who used it & thought very highly of it back when pretty much the ONLY way to have any internet access was via dial-up service & IBMnet.
This incredible OS vanished into the sands of time mostly courtesy of a sort of backroom deal between the (then) King of Redmond & IBM.
A bit later, loads of its features coincidentally (magically ?!?) visibly became the windows OSes we all got to use for a very long time after it had been disappeared.
Despite its near total obscurity, today - very quietly - lots of mission critical systems still depend upon it, hospitals, for example, and last I heard NASA is also still using it.
OK, OK, enough blather (finally !!) - it looks like this:
And here's its logo:
Why does any of the above matter AT ALL ?!?
Well, if you live in, or visit NYC - most likely you've been among the ~5.7 million people daily who ride upon the New York City subway on an average weekday - and guess what ??
OK, 'nuff about that for this minute - this next bit is just plain funny IMO - but don't visit the site if seeing the F word in print bothers you:
It clearly illustrates the effect that handheld devices have had upon website creation in general, and so very well - it actually got me to LOL !!
Now, to finally finish this (TL:DR ??) message, here's more info about OS/2 if anyone cares to look:
What is really funny to me is that I still have my real, genuine, official OS/2 tee shirt that IBM gave me (though it is a bit worn out) and did have both the red & blue box editions of OS/2 Warp until I cleaned out my old stuff & gave them away to some collectors.
So - if anyone has read all of this - perhaps you can see the contrast in all the above which has truly made my day !!
