I love Windows 8, I heard bad rumors that turned me away from it, but when I tried it and I got used to it, I really like it.
Also for you guys wondering the start button isn't gone, its just been hidden into a corner, and if you right click on it you get a legacy start menu sort of thing thats like the old start menu.
Apps are optional, but I like them, you can still install things the old way, and you actually gain performance and speed if you upgrade and you meet the requirements.
I like it more than XP, but XP will never be forgotten.
You guys should upgrade if you can, its not bad at all, theres just bad rumors about it.
