Ableton is of course the dogs danglies, but at the end of the day it's all about having fun with what you're doing. Playing vinyl records on the decks is great fun! Having a good old mixing session with your mates just isn't the same if you're all taking it in turns to have a go on the laptop. As long as people enjoy playing records then there'll be a place in the market place for vinyl (even though it may not be as lucrative as it was 10 years ago).
