Apple didn't have to nurture anything for me. I was on Android for 6 years then got an iphone and it was like someone took the rocks out of my shoes. Friends on android now say they have gotten better but I tried their phone and it was immediately back to the super unintuitive crap I always knew with them.
That said, I think Xbox is the much better designed hardware and operating system, but I hear from devs it's the other way around for them. It has always from the beginning been the story with Sony that they are better to devs and I think that has been the real key for them. Being 100x better than Microsoft at marketing just piled onto it.
Use CDs instead of cartridges and not censor so hard. That was it, really. Way more content could be fit into the games, massive profit difference for the devs, and gamers could get the games for 1/3 the price after not too long. It was win/win/win.
