Ok, I’ll pretend to be a VC. So you make a WebOS game/app. What kind of users do you expect to have? A whole bunch of cheapos who bought the tablet because it was $99. And how much do you think those people will pay for your app?
Next question. Word of mouth. If those people like your app, they’ll tell friends. Will those friends have WebOS tablets?
Let’s talk about the lifetime value of your code base. How long can we expect to make sales of your app? After we have saturated the market of existing Touchpads, will there ever be another piece of hardware running WebOS to sell to new customers who might buy your app?

Right now, I’d say this is a cherry-picking exercise. If you can port an existing app to WebOS and make money on a short-term basis over and above your porting costs, fine. Otherwise... Android and iOS are the two front-runners with Windows-Phone-whatchamacallit a distant third.IMHO.
