That's too bad.
It was pretty easy to write off Windows 3.1, and continue to be a solid solution on MS-DOS and with Netware, etc.
But Windows 95 had a lot of fanfare in advance that suggested it would have much better uptake. And Windows NT in parallel was developing a credible foundation, and it got the "new shell" as an option around the time of Win95. My recollection at the time was that the writing should've been on the wall, that Windows was going to be the Microsoft platform.
If WordPerfect was slow to move, that's a bad combination with, er, not as direct of access to the platform teams.
