rPi is probably the most aggressively priced, but you talk about it like that market didn't exist. The BeagleBoard is probably the closest, though that was designed more as a dev-board for ARM processors and not a mini-computer like the Pi.

For most practical purposes, it didn't. What existed were either inferior to rPi and more expensive (>4x) or approximately equivalent and much more expensive (>8x). It has had a significant positive impact on the way instruction is given.
