The OS/2 Warp commercials blew my mind in the mid-90s, and they never even once showed the system. I was a Mac person at the time, and would have been all over OS/2 if I'd had the chance. But I was in a very small town, this was the world with a pre-functional-WWW, and it was just impossible to find anything but System 7 and Win 3.1 at the time.
Then I saw a NeXT slab and it was all over.
