Well, I'd disagree that Color's valuation doesn't affect their business model. When you take $40M then you're saying a few things including: we're going to build a great (ala expensive) team, we're going to build it fast, and we're going to get users right away. That impacts one's business model greatly.

Also, I don't want to build products to appease investors. Cashflow is the goal, investors are a less important detail if you want to go that route.
