Apple, i.e. Steve Jobs, stated multiple times that they don't have to build everything themselves, that they aren't good at everything, and that strategic partnerships with outside companies is important. If my memory is correct, Jobs even said that one of his biggest mistakes in his early career was not realizing this.
This is true; and within Apple's success. I guess I see them having an incredible ability to meld things into their own.
A strategic and public investment, like Twitter, feels unlike them. Twitter seems to be the news, not Apple.
The AuthenTec acquisition, however, feels very Apple. They have a vision, they found a partner (and for some reason, acquired them). If it weren't for the purchase, AuthenTec would still be unknown to me.
The biometric integration will be, bar none, an Apple event.
