First impression (half hour). WOW
Turn on, play, and song 1 pattern 1 (called New Car; good marketing) starts playing. Interestingly enough, after the initial kick what sounds is a synth chord pluck. 7 plucks spread in the 16 steps, no more drums. Pattern number 1 is already making a statement that this is not just a “drum” machine.
Next Pattern, and now a breakbeat-like rhythm starts kicking. 175 tempo. This feels good. I start punching effects, jumping patterns, changing songs. There are lots (lots) of beats (rhythms) and kits (sample collections) to try and combine. Also 20 songs (projects) that give you an idea of the possibilities.
I start creating a new song. 4 tracks, 16 steps, step parameters… Having done this in other devices, everything works as expected. I wonder how punch effects, master effects and another instrument through the line in would combine but… it’s Saturday, I have Saturday things to do, and I need to go.
I’ll get back to this later. Happy to answer questions if I can. Disclaimer: I’m a very amateur dude very bad at creating drums – and this is why I got this, to save me most of the hassle. 
I can see myself combining and tweaking presets more than creating things from scratch, and I’m not a live performer at all. Bitwig user.
EDIT: oh, the touch feel and weight… feels very good and solid and sturdy, but also sophisticated. Very subjective, of course.
