When creating a new GUI, is WPF the prefered choice over Windows Forms?
Most restrictions and tricks with windows forms are common to most programmers. But since .NET 3.0 there is also WPF available, the Windows Presentation Foundation. It is said that you can make "sexy applications" more easy with it and with .NET 3.5 SP1 it got a good speed boost on execution.

But on the other side a lot of things are working different with WPF. I will not say it is more difficult but you have to learn "everything" from scratch.

My question: Is it worth to spend this extra time when you have to create a new GUI and there is no time pressure for the project?
