WPF has a lot of advantages, it's perfectly sane data binding mechanism being one of the most outstanding ones.On the flipside, many people (meaning companies, mostly) have refused to switch from WinForms to WPF because of the "blurry" looks of applications written in WPF.
This blurryness goes back to two mechanisms:
1)Text Smoothing
Instead of relying on the system's ClearType mechanism, WPF does it's own thing-a-magic, which is blatantly inferior to the aforesaid. In fact, WPF smoothed fonts are a definite way to headaches, if read for some time.

They might be useful to integrate text in images, though.For business applications (displaying data grids etc.) this is a K.O. criterion. Nobody wants to have to take their glasses off in order to achieve readability, and nobody wants their software deployed along with a pack of aspirins.
2)SubPix...
