On my (old) test rig i get an experience score of 5.9 for Vista.With Win8CP i get 6.9. Starting win8cp to the opening screen (not desktop) is faster than vista and a bit faster than win7 but vista/win7 open at the desktop. To see how you would work with a touch screen note a couple of items you have to reach with a mouse/cursor and "pretend" to touch the screen.Instead of a small movement of the hand/wrist you have to move your complete arm and poss part of your body! Back to win8 - you have to remove the opening screen by swiping the picture away. Then you have the log in/password. Next you get the "metro" screen - a num of simple square icons - one for each app you want to keep ready to use.One of these is "desktop". Up to now i think these screens are a waste of time/effort. If you right click at this metro screen you open a small area at the bottom and in that area you have an icon "all apps".Click on this and you have a screen with (in my case) over 50 items/apps. I do like that bit. Click on the desktop icon and you finally get the area most of us are used to. You can remove win8 developer and/or win8 CP - BUT you have to load in a way that lets you remove it without harming your other programs.
