So I take it you've never tried Ness ( http://www.likeness.com/ )? * Ratings don't need reviews * Personalizes like Netflix * Shiny mobile app (Disclaimer: The CEO is a good friend of mine)
Wow! Looks cool! Why no Android app? Nowadays its cheaper to develop for all platforms and a mobile web site than just iPhone...
What do you mean cheaper to do more? It's obviously cheaper to just develop for one platform, and maybe to do a mobile website, vs. crossplatform.
It might be worth the extra users/revenue to be crossplatform, but it is definitely easier to focus on a single platform and do it well.
