He’s written an article titled Microsoft Win8 Tablet Is NOT a Game Changer. The article explains that it was never meant to be, what a game changer is, and gives a pretty interesting discussion on the history of game-changing innovation in the area of handheld devices.
Then he discusses why Microsoft missed making the list.
I thought it was a wonderful read, and would have greatly enjoyed the article from any author. That it came from my cousin, Adam Hartung, is just triply awesome!
