Rather: It took them two more releases until they offered a version that had a price tag (setting the price was a conscious decision by Microsoft) that made a Windows NT derivate also affordable to non-professional users.

I don't think it was that simple. Hardware support wasn't good on NT, and it had poor compatibility with a lot of 9x software. These were two things that MS considered obstacles at the time.
