Do you have concrete examples that are much harder in the web than in native? When I started developing, I very much liked the web technologies for not being in my way - you have to learn their pitfalls and so on, but once you're up and running, you can do anything you want. Compared to that, every time I touch a native toolkit feels like an absolute nightmare the second you leave the trodden path. Even things like "changing the color of specific parts of a control" are often times either completely impossible without fully re-implementing it, or lead to bugs that make you wish you didn't try.
