Twenty-eight years ago last month, I left Univac to form my own software company based on the new microcomputers. Partly I felt Univac was stuck in old paradigms of big boxes, and partly I wasn't doing very well myself on creating new ideas.
A few years after that, Burroughs bought Univac and called the new company Unisys. Unisys continued making mainframes for a few years and slowly moved to being more of a consulting company.
Before that really happened, I moved to using Macs only and haven't stopped since.
Now, Unisys is now considered a "technology services specialist", and some Motley Fools think that Apple and Unisys may reach some agreement to help Apple seek enterprise and government contracts.
Also, once companies started adopting personal computers, the "gold standard" became PCs and Microsoft. The Mac was a toy and not a business computer. Now "Apple's Tim Cook [acting CEO] says the iPad is being deployed or piloted in 80% of the largest corporations today, and 88 of the Fortune 100 companies are testing or using the iPhone."

And older readers may remember all the predictions of Apple's demise in the 80s and 90s. I read somewhere that Apple now has more market value than Microsoft.
And as I've said many times before, we ain't seen nothing yet in technology.
