Thanks all. @abbasmehdi I should have mentioned we've had various iterations of the product already where we got feedback from customers: that's what I meant by being perfectionists, not that we're sitting in a vacuum somewhere all by ourselves :-)
@TuaAmin13: I appreciated getting his feedback and so on because you know how it is: I've been getting great feedback from my beta testers etc, but nothing from adults per se. My last meeting with him though I really did get the sense he was trying to piggyback off my work, where he asked for a ridiculous amount of equity for approximately one month of real "work".
You guys have given me great feedback. I'm going to ignore the guy and just focus on getting the product out.
