I loved Word Perfect 5.1 for MS-DOS (I wrote an emacs keyboard emulator for it). And when Windows 3.1 came out and everybody was moving from MS-DOS, most of our lawyers said, "of course we should move to Word Perfect for Windows, it's what all the law firms use." But our clients were all using Word for Windows, and so the group looking into it said, "who GAS what other law firms are using, let's use what the clients are using." And we did.
