Windows 3.1x was the first version of Windows which was actually barely usable, did not screw up as badly as Windows 2.x, and began getting some major application support from companies such as WordPerfect and such products as Autocad. It also was the first version of Windows that had Netscape, and the original NCSA Mosaic Browser. It had SoundBlaster support, and some early TV card support such as the Reveal TV300.
