I used this for a while. It was a great system for running a couple of DOS BBS instances (on two lines![1]) in the background while also running Windows 3.1.
Although, I can't imagine that this use-case was all that popular. It was a great glimpse of what was possible on the hardware of the day, but still seemed like more of a gimmick. But given that we run everything on virtual servers these days, it was really ahead of its time.
