What's important is not the fact Nintendo invented it all, the idea was in the air for years and years and we all know that...
It's the fact they took the RISK to introduce something new (AND well thought)... and with that "new" tech, a brand new generation of games build around it... exact same thing for DS...
Not being conservative is always a challenge, and we all can see how they already won that (these) challenge(s)... DS and Wii are great consoles, and Iwata is a great president, who took risks that are now paying...
That's the reason why with these two products ONLY, Nintendo became the 4th largest company in Japan, while Sony (with many many more products out there) isn't even in the top 10 anymore...
