Pro: - The idea is sound. Value-added services like this are exploding all over the web - The value-prop is clear - The feature set is clearly explained Con: - As others have said, the pricing would work better as pennies per upload -- makes it cheap for rapid prototypers, whom are going to be a big part of this market - Uploading via a third party raises privacy issues, even if you're not providing storage - I suspect the market here is too small: it's the gap between people who know how to integrate your product and people who know enough to build it themselves. However, it's a big Internet and I've been wrong before about the sizes of markets (for instance, Tumblr!) So go for it, and good luck :-)
