No, I think they vanish because Microsoft screws them up with their control freak “we will force people to use our stuff because there will be no alternative” marketing strategy.
Microsofts thinking is not “build a better mousetrap” it's “build the ONLY mouse trap”. The problem is that this no longer works as they now have competition they can't bully out of business.
I'm not a MS basher and I do like the company but there is truth to the Microsoft does not know how to innovate theory. I used to think they lost their way when they tangled with Netscape. Now I'm starting to think they were NEVER a true innovative technology company. Just look at the way they responded to the threat of Netscape competition and you quickly realize they were not interested in making a BETTER browser, they wanted to make the ONLY browser.
I agree. MS is good for the basic stuff like the OS, SQL server, Office, and that’s about it. Those things serve us all well. They try to branch out, but just never seem to be able to.
