Microsoft's unveil of Windows 10 yesterday was one of the most humble, apologetic things I've ever seen in technology. After years of defending Windows 8's weird mashup of new Metro and old Desktop, there wasn't a glimmer of hubris or righteousness on the face of Microsoft's Myerson or Belfiore as they showed off an early version of Windows 10. Windows 10 is basically the upgraded version of Windows 7 that we've always asked for -- but is that a good thing?
