Yes I use it regularly. It has more or less the same features as the commercial software. Where it falls down is with the quality of the audio effects which are nowhere near as good as the ones you find on Serato or Traktor, but they're getting better all the time. On the other hand, you can customize almost every aspect of Mixxx. I have an unconventional controller setup so created my own skin (XML and CSS) and MIDI controls (Javascript) and that has really helped my 'creativity'.
