I only saw him pull it out of his under arm, open it, shut it, and put it back under his arm and walk away and set it down (cameras didnt exactly follow, they stayed on GA). I find it weird, just plain weird that he would have a laptop to read a speech such as one that he gave. I dont think it was a webcam on his part, it had to have been taped, she can see it anytime from JB's computer, but more likely IMO from JB's webcam to them instead of them to her...IMO, I think it was an IM or email that he was looking for from KC to say she was online, that she is the pillar of strength, whatever, or possibly even recording only his part of the service to immediately reach KC via Biaz's computer.
Whatever it was hinky especially for someone that wants the public to stop speculating...he did an Absolutely exceptional job of avoiding that didnt he, using a laptop instead of paper, using CMA instead of his nieces name, not wearing a Caylee button, nor wearing a tie or jacket (my personal opinion of how respect is shown at a memorial regardless of the deceased connection to you) he did it so well, he was absolutely radiant.
