Tightly integrated hardware and software, when done right, can certainly lead to a workflow that really changes the whole experience, making everything a lot more fun and really quite a different experience to using a computer with a mouse.
I had the original Maschine not long after it came out and I was impressed, although its taken a good while for the software to get enough features to keep people happy. The newer top-end model looks great, shame about the price. Most competitors will take a while to catch up with sort of integrated product, though quite a few are trying and the competition between them should lead to this stuff maturing nicely over the next few years.
