Well I've got it installed and running now - so far not too impressed as images in WPF are still blurry and they seem to have removed the one property that helped make them less blurry! (RenderingOptions.BitmapScalingMode)

Also, when in the WPF XAML editor window, the little icons in intellisense for properties, namespaces etc get more blurry the further down the list they are. The ones at the top of the intellisense window/list are crystal clear but at the bottom they are blurry :S

I like the new start page though and it does seem to be a little bit faster than the previous BETA (not loads though)
