I like Canute, I really do... but the statement that not many DJ's can control 2 sliders at once is rubbish. Every club DJ I know can do that and more. I was not directing my comment towards Club DJs. It's really not hard. Throwing down 3-4 tracks ar once, all on beat, without using sync and just going by ear... THAT is hard! You have to use all 4 volume sliders, plus the crossfader, plus the pitch sliders of all 4 decks, plus any effects you throw in.
I have to say, when you use automix, you are not just a "push play" DJ, IMO you are not a "DJ" at all (not Canute, just generally). You are letting the computer play all your music, while you sit back and play on the mic or whatever. That makes you either an MC or a slacker, one of the two. I can definitely see using Automix for dinner music. That is generally when I use it. I said so didn't I? I would too. Who wants to throw down some Kenny G for 2 hours? But to use it to actually DJ? Come on now!
And when you use Automix to make yourself "a better DJ" you are not BETTER at all! YOU have taken yourself out of the equation and turned your laptop into a DJ.
