That's a mischaracterisation of my comment. Toyota is about improvement/perfecting (Deming's "quality", Six Sigma).
The examples I gave are about new product categories. To repeat one of them: before Sony, there was no transistor radio. They created not just one, but several new product categories - twelve, by Christensen's count. (Unfortunately, Sony didn't create any new product categories without the founder. e.g. the playstation was a great product, but consoles were an established product category.)
That is, it's not the getting better at something, but the creation of something new to get better at (hence Christensen's interest, as the coiner of disruptive innovation).
[ BTW: I can't help but think that the post-war period in Japan somehow enabled this creation of new product categories. ]
