Native Instruments just released version 2.0 of its beat production software Maschine, and alongside it, Maschine Studio, a hot new hardware controller. As its name implies, this is some serious music machinery.
The key advantage to the Maschine ecosystem, as with other Native Instruments products, is that it's a focused approach. Unlike humungous digital production suites like Pro Tools, Maschine is all about producing beats (or as NI would have it, "Grooves"). Part of what makes this focused approach so successful is that the company makes its own hardware to go with the software. It's no surprise that NI competitor Ableton has veered in the direction as well, producing hardware for its extremely popular Live software.
