Gamespot's Inside E3 blog points out that Sony didn't steal their motion-sensing PS3 controller from Nintendo-they stole it
from Microsoft and Logitech:They didn't steal from Nintendo. They actually stole from Microsoft (and Logitech). The picture you're looking at here [follow link to see pic] is a picture I took of gyroscopic, motion sensing controllers that Logitech and Microsoft manufactured for the PC in 1999. Yes, 1999 as in more than seven years ago.
...I just wanted to point out that this idea was soooo 20th century, and immediately flamed out on the PC because they were honestly more of a novelty than they were practical.
Of course, that would imply Nintendo stole their novel and impractical- exscuse me-innovative idea as well.
