Rich Wong, general partner at Accel, interviewed HP executive Phil McKinney at our MobileBeat 2010 conference this week.

McKinney danced around the notion of whether HP would build a “slate,” or touchscreen tablet computer. Here’s our video excerpt of the Q&A where Wong quizzes McKinney about the purchase of Palm.
