Depends where you go. The clubs I frequent in Melbourne rarely have anyone playing with a laptop. Having said that, the bar I work at (cocktail/tapas/club venue) is full of autosync whales on their MacBook Pro's. I guess it ultimately comes down to the scene you're in, and where you're based. Good talk andy i think that usually the bigger the club the less people with a laptop and midi controller setup like the s4 etc. just because they usually hire dudes who have been doing djing for a while and are most likely going to stick to their cds or usbs. That's not to say all of them do as I've been to many of the bigger clubs in newcastle where the dj is using a laptop.
