Correct me if I'm wrong but wasn't the original G5 released at WWDC.
Yup, 2003 WWDC to be exact.
iPhone is opening the floodgates to Apple, with the only thing holding it back is AT&T (in america, then again, if I can afford an iPhone, I'd be more than willing to pay for AT&T, which makes the argument moot)
Why did all those keynotes in the past focus so much on the Mac?
OS X, Steve Jobs and co. wanted to nail it into our heads that not only did they have the fastest computers, but the most advanced OS in the world.
But then the iPhone came around with the revolution of Multi-Touch. Apple is molding around a Portable lifestyle, why do you think they are cutting down OS X and cleaning it up in Snow Leopard? Portable devices with very little space, such as the Air, do not have the space and would help big time if the OS is slimmed down.
So to sum up my long ass post, what did I think of WWDC 08? Apple is AGGRESSIVELY pushing out iPhone, willing to sell it at the same price as an 8 gig iPod Nano just to get the customer base to grow. I think it's great. I know for a fact that when I do get enough $ I will own an iPhone. No point for a laptop for me if I have an iPhone that knocks out a laptop/iPod/and any other Phone.
