Excellent job Microsoft. Windows 8 is simply amazing. I love it.
Windows 8 features the awesome Start menu which gives you access to your desktop, music, games, apps and more. The GUI is extremely polished and it is overall more user friendly. Plus it is much faster than 7.
And yes, it is compatible with Blockland, although the launcher is a little slower. Be sure you have your key though, because installing 8 can mess up your key.dat which happened to me for a second.
However, the installation process is slow and tedious. Users of Dolby Home Theater and Advanced Audio will be without it until Dolby makes a driver compatible with the operating system. Also, for now you might not be able to change the MIDI driver you want to use.
Overall, I give Windows 8 9.5/10!
