It was all really happening a decade ago this week. Earlier in the week a decade ago, the iPod was unveiled. Later in the week -- ten years ago today -- Microsoft officially launched Windows XP. Astonishingly, they're both still in heavy use today. Sure, you can't buy Windows XP at a retail level any more, but that hasn't stopped millions of computers the world over using it. One of my kids' laptops is still a Windows XP machine (it'd never handle Vista), and I often spot XP in the wild. What about you -- are you still using an XP machine?
