After installing Ubuntu 10.10, I had a strange feeling I was seeing something that was already old. Yes, Ubuntu is a fantastic desktop system, and yes it's better than Windows. But today, in 2010, that's almost a given. And that's not enough. The IT world is changing, and PCs themselves as a whole are getting old. The mass is moving towards tablets, mobiles machines, and netbooks. Ubuntu, the way it is today, might be the best choice in a dinosaur world. I can't read Mark Shuttleworth's mind, but I can only guess this is exactly what he felt when he decided to switch to Unity (for the UI) and Wayland (for the graphics architecture). Let me explain what all of this means.
