I use it every day
Well. If we talk about WindowBlinds, it just replaces the bitmaps, that Windows uses for the buttons, menus, scrollbars etc. with other ones (whatever they are). Therefore You can change Windows to look like a Next machine or BeOS or Mac or whatever other operating system (or some fantasy system).
Therefore, using Windowblinds alone doesn't make Your computer behave like MacOSX. It makes it to look like one. Eaven worse. As Windows uses many sets of the graphics and some apps use their own, windowblinds isn't capable skinning them all.
So. Some bad habits remain (windowing the maximized screen for excample). And some functionality cannot be there (transparent menus, Dock).
What You see on the screenshot is a replaced shell of Windows using all the Stardock's packages. I tried it, but as it took helluva configuration time, I left it behind. Also Dock did look ugly (as the bitmap icon's can't be scaled the way vector icons do.). And the Dock wasn't really alive (the content of the dock wasn't dependent of what programs do I open) Stardock has many packages. You need at least DesktopX to do this.
Below is the picture with the windowblinds and IconPackager as it looks on my desktop.
. I may try this for VPC
