Starting with prototypes and mockups? Great idea. Definitely the only way to go. Deliberately misleading customers into thinking those are actual screenshots instead of mockups? Ugh. Part of the reason it's so hard to sell software is that so many people have historically sold vaporware, which makes life harder for those of us that go out of our way to be honest with customers about what's implemented, what's a mockup, what's planned, and what's promised. Customers don't trust us because they've been screwed over by decades of shady sales guys. Please, let's not contribute to the horrible, shameful record of software companies lying to customers in order to get sales. (And yes, I personally count "deliberately misleading" and "outright lying" as approximately the same thing: if lying about X is unethical, so is deliberately misleading someone about X.)
