Kottke on one of Apple’s potential weaknesses:

Someone should figure out how to leverage Facebook’s social graph to make the phone/app/gaming/music/video experience significantly better than on the iPhone/iPad and then partner exclusively with Facebook to make it happen. 

That someone will be Facebook themselves. 

He also notes:

the Apple products & services that Apple does well are the ones that Steve Jobs uses (or cares about) and the ones he doesn’t use/care about are less good (or just plain bad).

That generally does seem to be the case. And it comes across in unveilings too.
