What's the point of the magic trackpad?

  On Twitter, Dossy wonders why the new "Magic Trackpad" from Apple.
    There's the the M-word again. Pretty soon I'm going to think it's a brand name™.
  Come on guys get with the program. You're in the middle of a "bootstrap". This is the next step.
  Apple has a new operating system called iOS. It's what runs on iPods (which they are phasing out), iPhones and iPads.
  What doesn't it run on? (Yet.)
  Why not? Wellllllll. Cause for one thing, the Mac is built around a mouse as a pointing device and iOS is built around fingers as the pointing device. So if you want to run iOS software on Mac hardware don't you need a little new hardware? Just a little?
  Come on, this isn't that hard. It's Software Evolution 101.
