WebOS is actually pretty nice to develop for, it just needs faster hardware with better battery life. Oh, and a way for developers to make money. It's a little rough that anyone can just shell into their phone and view all of your source code.
Since, 1.4.1, I think things have changed. I get 3 days out of a full charge now which is close to making me forget my blackberry.
I'm not terribly familiar with webOS/palm ecosystem, hence the question: what's the usual channel for selling a webOS app? all this cloud talk etc, does that mean you can chuck up a web site/app targeted at webOS and start charging for it?
