During the late 80s in Hungary, the Amiga certainly was a big thing, even in schools. It's interesting, I split my childhood between Hungary and South Africa, and pretty much along the timeline of the 486. It was a remarkable demonstration of how positive an effect technology could have on the learning experience. For me in a rural school it wasn't until the mid 90s we had 486PCs with CDROM drives and going from Britannica to the searchable rich media database that was Encarta was a massive force multiplier. If you were doing primary / secondary school during the 90s, you'd have had to do projects where paper encyclopaedias were your primary resource. Encarta was really a product of that time. Games and applications were evolving at break-neck speed and the pace of change really made you feel anything was possible.

So with the emergence of VGA and Super VGA, widespread availability (and relative affordability) of 486 DX class PCs, Soundblasters and Optical Drives, the PC overran the other home computers. I know the Amiga was well ahead of the PC ecosystem for a long time in capability but it never hit schools (at least where I grew up in South Australia) like PCs did. That whole period of the PC industry where 'multimedia' became mainstream was pretty magical.
