Exactly. Nintendo changed what the player has in her hands. They did it with the N64 (analogue control) and they have done it more radically with the Wii. I think it is Peter Molyneux who has said if you want to innovate in gaming change what the player has in her hands. Software is important, but ultimately secondary. I think this will probably be the case in any big changes we see in personal computing as well. The mouse and keyboard work really well for some things, but as new input systems like multitouch and who-knows-what-else come along real changes will begin to pop up in software; not the other way around. Of course you might argue multitouch is a software innovation...
