Not sure if this would be considered a GUI, but check out this video from 1968 I was 2 months old when this occured. http://www.youtube.com/watch?v=JfIgzSoTMOs
I was running GEOs on a C=64 before that. Don't even bring up how much farther advanced my Amigas were by that time. MS is always late to the party.
I agree, I was running PC/GEOS on my x86 and 286 machines back in the day. It had a very clean GUI, worked with all DOS applications and came with an office suite that was compatible with Word, WordPerfect, WordStar... And it ran in 640k of RAM. Ah the good old days... *sigh*. Did I mention it was way better than Windows 3.1? I didn't give it up until Windows 95.
Ah, brings back memories! This article / photo gallery seems more like a flashback in computer history.
I actually worked on a Xerox Star at one point. My client was a PR firm for a big corporation. One partner had a Mac, the other a PC. Their client was a big corporation, wanted to send files to the Mac partner to be published - time sensitive press announcements. The Xerox had no comm software, but their version had a dos emualtor. I installed a freeware com program in the DOS window. I wrote a script to dial the Mac at the PR firm and send a file. Fun times. For the record, the Xerox GUI was kinda klunky compared to the Mac OS. But they did have these huge monitors, great for doing word processing and seeing the whole page at once.
Actually the first Mac came out in 1984. The title should have been "1991 - The Year the Rest of Us Got GUI."
Don't you remember the 1984 Apple commerical at the SuperBowl, launching the Mac? Who could forget it? http://upload.wikimedia.org/wikipedia/en/5/5d/Ad_apple_1984.jpg Why 1984 won't be 1984......
