I'm using Win XP on my LT's & Home Pc's...I'm used to it and never have any problems how much better is Win 7 or 8? I'm a bit weary that if I up grade to a new Laptop running Win 8 things that I'm used to doing will be radically different & have a difficult learning curve and will some of my programs actually still work on Win 7 or 8 like Vanbasco, EMC styleworks 2000, Mixcraft 5, etc, etc,?
