Yeah, I have absolutely no business use case for this, but I do have a spare 30" Dell in my office and would love to play around with this. I wouldn't pay more than $10 or $15 per month, though.
I think the pricing should be setup more of a way to get you hooked on the crack. You give some crack for free, get addicted, and want more. I think most corporations have a need for many dashboards. So what about two for free and get them addicted, and they want more?
