Did you take a look at the conference ctyhntr is considering? I'd characterize it similarly. Most of the sessions and workshops are focused on more advanced topics.
Everyone learns things differently, ctyhntr may not be able to absorb the free session videos or the Stanford iTunes U course or .... as well as he does in a dedicated environment like a conference.
All I'm saying is that if you think a develepment conference might be the right thing for you, and are willing to spend $1500 on it, consider 5 days at WWDC over 3 days at iphonedevconf.
