So what is Microsoft's most loved, most stable and highest quality product?
The Intellimouse was a near perfect price point of quality, reliability and correct ergonomics for me. I bought three or four of them and still have one around today. Kinect was an innovative product that set-up easy and worked as advertised.
Other Microsoft products of the time, such as Commodore BASIC V2 used in the C64, were not that great, though the compilers for CP/M were quite OK.
Everything developed by Microsoft after the early 80's... let's not talk about that :). My work environment is Microsoft-free since I stopped using my C64 and Apple II for everyday tasks and I'm happy to own some computers for which Microsoft never published any software - NeXT workstations.
“Develop for it? I'll piss on it.” – Bill Gates, in response to InfoWorld asking if Microsoft would develop applications for the NeXT Computer.
I thought that the Atari ST was another platform without Microsoft software, but there was a version of Microsoft Write published in 1987 (https://www.atarimania.com/utility-atari-st-microsoft-write_...).
