SO far win8 is like Win7 only with a very screwed up and under optimized start menu that when clicked becomes a Icon driven whole screen menu.
A few things they need to do IMO is allow you to make folders or allow programs to install there folders then link an app for one button clicking, right button clicking will give you a sub menu with more options. Or soemthing of the like, having every file thats installed be put up as a Icon is a bit....silly....... (goes off to install photo shop CS 5 on it).
Also would be nice if I could select multi icons for deletion or unpinning......
