Yes I like WPF's model, but it's not worth investing my mental energy into something that is self-obsoleting. Although you can make a career out of WPF, there is a lot of stuff that needs to be maintained, and trading companies around where I live seem to favour it. Probably because they use it to make internal software, they can dictate everyone uses Windows, and they need to build stuff fast but it also needs that native performance, flexibility and power you don't get with HTML.
