Apple CEO Tim Cook's conversation at the D10 conference tonight ranged from Apple's philosophy on secrecy to whether gaming was in the company's future, with plenty more in between. Now All Things D has begun posting video clips from the event, including Cook's thoughts on the current smartphone patent wars and why tablets are a separate category from PCs. The seven clips (as of this writing) will give you a good feel for what Tim Cook is like as an interviewee and provide some insights on his thinking about Apple's future (the answers, if you can't watch the videos, are "mellow" and "justifiably optimistic").
