>>I haven't noticed any slowness yet myself but I only started looking at it. I did immediately notice that it is entirely WPF in design and opening VS2008 rdlc files requires a conversion to take place. Haven't tested bringing in an entire project or solution yet though and may not have time for that for awhile. The look and feel is really really nice though---like the x on the tabs for closing (like IE tabs) instead of all of them on the one x in the top right corner of that window.

>Thank you for your input. Since I don't have VS2008 and don't even know what "rdlc" is, I won't be needing conversion. I will be starting my learning of WPF; that's all. It would be nice if for WinForms application they (MS) would improve the IDE to allow for visual design (similar to what VFP does) but I am not holding my breath.

What do you mean? There are plenty of visual design tools in WinForms. Now in VS 2010 they exist for WPF as well.
