Boy did he!
I spent hours reading about Lisa, Xerox/PARC, and Taligent yesterday after this thread started. It was a third time around kind of repeat exposure for me, but I had forgotten a lot of details (and never knew many of them).
It's shameful how much time and effort goes into development of things that end up being abandoned. I was stunned to read about how Lisa's OS was superior to Mac OS in several ways; things that didn't come to Mac OS until over a decade later (some of which was supposedly why Lisa was so expensive; such as protected memory hardware requirements).
I had already known about Apple's failings to modernize Mac OS, partially because I was a BeOS advocate and involved with the user community, and there was a lot of interconnected goings on back then among all of these entities... but re-reading the long story of Taligent and the associated development/companies... it's just so nutty to me.
No matter how much great stuff has come out of competing businesses, it seems like so much more has been squandered as a result of same competition, even with businesses supposedly under agreements to cooperate for the betterment of everyone. For a change, I'm not even talking about how Palm, then Access, squandered Be's IP.
Related: I am again thinking of how MIDI 1.0 is 40 years old, has had almost zero improvements in all that time (MPE being simply the formalization of existing recent new methods of implementation), and that MIDI 2.0 is still mostly nowhere and nothing... This isn't squandered development; it's a total lack of development.
