I didn't really like the way the laptop judders slightly (especially in the opening 10 seconds or so) because the images don't quite line up. I'm not sure whether it was a conscious decision to do it that way - obviously taking identical pictures is hard, but not impossible, though doing the whole thing digitally would probably be easier. Odd choice, if you ask me.
This is a keen observation that make a surprising conclusion. I made the same observation but had a completely different reaction.
The stuttering was actually a motif to show this are pictures of different laptops of real people. It also completely tied into the music which was of a stuttery and impactful tone. It was obviously an intentional technique. You will notice that the laptops were also scuffed and looked used.
The whole ad was about how personal a macbook is to its owner. I think apple have been concerned mac's are now so 'mainstream' they want to encourage the view that you are your macbook.
