I have Windows 8 Pro on my desktop computer and one of my laptops. I consider myself having the best of both worlds (Windows 8 and Windows 7). There is a learning curve, but the efforts are rewarded (imho). I have been using Windows since Windows 95. As always, when a new version of Windows arrives some third party programs will get left behind, along with device drivers and the sort. I also have software that I paid a lot for that I cannot use on Windows 8. However, I really like Windows 8.
I have installed several Stardock Products and they work fine. I also have several legacy programs that work on Windows 8 Pro.
For those who are using Windows 8, I have a few tweak tips (if you don't know about them already).
1.) Windows 8 God Mode Tile script can be found here:

2.) Windows 8 by default does not "shut down" when you click shut down, but rather is hibernated. This is done to enhance a faster boot. The faster boot option can be turned on or off in control panel power options, or manually overrode. Full explanation can be found here:

You can also hold down the shift key while clicking on shut down, and keep the shift key down until the computer shuts completely off.
3.) Little known utilities included in Windows 8 can be found here:
