wat are most dj's using for playing out now if they are mixing from a laptop?

seen a few big techno names using ableton to just mix trax which i think is valid even if it doesnt require any beatmatchin dont think it matters as long as the tunes r fat.

is ableton the one for live , i say live i also mean just laptop mixing ?

i am deckless at the mo and just missing being able to have a mix i think.

wats everyone using ? abelton, tracktor or watr?
