Walt Mossberg and Kara Swisher were joined by Steve Jobs on stage last night at the All Things D conference to answer questions on where Apple's been and the direction they're going.  Out of the gate, Mossberg questions the decision to cut Adobe Flash support from the iPhone platform.  Jobs insists it was a technical decision and told Adobe to come back with an optimized version for the platform to which they never did.  Check out Jobs' full response above and the long, long list of videos from last night over at AllThingsD.  There's a lot to take in and it's all quite interesting.
