I have recently started using Silverlight for LOB applications. Along with
patterns like MVVM, Silverlight 4.0 i think is mature enough framework to have an Business app built, although I must admit it is high effort if you are not using RIA services.
Now I hear about HTML5 as the future of Rich UI development. How long before HTML5 is mature enough to build LOB apps? Will it have some sort of data binding framework for its controls?
I was hoping I do not have to worry about HTML5 for another couple of years
