One of the things I consider when seeing new technology is, whether it will impact my workflow in a good way. I don't consider something that has a different interface and input system, that does not improve the speed or quality of the work, or give me any other advantages in my work, to be innovative - it is just different. Photoshop is Photoshop - editing on this system will take exactly the same amount of time as on the regular computer - so where is the innovation? Oh yeah, it's expensive - so there must be some advantage, right?
There are other reasons I doubt I'd buy into this system as well - ergonomics being one of them. I found graphics tablets played havoc on my back and neck after being bent over them for eight hours a day over a year in one job I had. Are they useful in some situations? Yes, of course, but the long-term disadvantages outweighed the advantages in my case. And of course, YMMV.
I make my living with computers working with design programs - I look very carefully at the ROI long-term both financially and health-wise before I invest in a new system.
I moved from film to digital because of the huge advantage in doing so - and I upgrade for the same reason. But I love my stick shift auto - it responds instantly when I change, and I hate automatics - they're so boring to me - so yeah, I guess I'm one of the old curmudgeons. Give me a stick on a mountain road anytime!
When a computer gives me that same thrill, I will buy it.
Cheers.
