Well, he's no Jobs, but come on, compared to every other technology oriented keynote...Apple and Cook are still about 10000000000000000000x times better. Every other company makes me cringe at the incredible amount of awkwardness.
Jobs was a razzle dazzle salesman in the purest sense. Using his charismatic aura to lure people in, he could get people to believe in magic.Steve was always on stage giving demos and showing how "magical" it was.
I admire how he is trying to bring back the magic that Steve brought, but in his own way. For example, the heartwarming video near the start... fantastic.
EXCUSE ME!! Despite what any perception of his mannerisms at 2012 WWDC you CANNOT use his first event which was the iPhone 4S event as a comparison or give it any fault. He was doing his very first product launch reason to be uncomfortable enough BUT he also had to hide from the public while doing the launch that Steve Jobs was on his deathbed as he was doing the launch. Not to mention keeping his personal emotions intact regarding Steve Jobs. The man died the following day.
