Time is money. And a lot of Windows XP users find themselves trying to save time by skimming through larger computer books in order to pull out the useful nuggets of info that are often placed within what we call sidebars (i.e. those Note/Tip/Warning boxes). The Killer Tips series was developed by Scott Kelby because he recognized how useful technology users find those cool "I didn't know THAT" sidebars that are peppered all over the other computer books out there. Windows XP Killer Tips is all about speed; showing XP users how to get more work done faster, while actually increasing quality. The whole concept is to help make you faster and more productive than ever using Windows XP.
