I just finished a week training in Vista and now I'm supporting tech issues with Vista. It's going to be quite annoying with the little things Vista did to make it "prettier" to the users, such as hiding most of the top menus in various apps. You now need to hit your Alt key to get the file, edit, etc.. menus. That and other little things such as no more Run diaglog box, unless you go into the settings and bring it back or do the Windows Key + R shortcut.
All in all, it seems a little more secure of an O/S and has some pretty interesting functions. Hope these business users are actually trained a little in it before using it on their own.
