I've heard this argument made a thousand times and I still don't believe it because there are plenty of vinyl DJs who don't interact and lots of laptop DJs who are pulling all sorts of stunts on stage to entertain the crowds.

What matters more than the medium is the individual who's playing from them.

I've performed a lot, both from a laptop and from vinyl (and a fair few times with both too) and anecdotally I can say using a laptop has never defined how much of a spectacle I choose to make of myself. The amount I've slept beforehand or whisky I've drank has a much bigger effect ;)
