Yeah man, that's pretty cool... well, not so pretty
1- I make and use circuit bent instruments (duh). Perform, record, etc.
2/3 - without using the machine, it's difficult to pass comment. It's got a multitude of functions which is always good. It would certainly suffice for gigging both improv noise soundscapes and beat-laden craziness. What does that thing weigh, for that could be it's downfall for gigs...
4/5 - It's got a lot of variety in it's functions and it sounds ace but it's layout looks quite clumsy in areas and lacks uniformity. It would certainly benefit from an overlay to separate each section, not only to improve aesthetics but to better it's playability. The drum and keyboard section look great aside from the cluttered buttons, perhaps rotary switches would help cut back on clutter and components. The dub siren and voice changer are a bit too close together from what I can see, but again, it all sounds beautiful and that the most important thing!
6 - ooh, there's always stuff to add. Patchable LFO, sequencer, delay... it's all good.
Hope i've not come across too critical but with a little refining, that machine would be the business!
