Windows 8 was publicly demoed for the first time about three weeks ago now at the D9 conference and it is still wowing people who see it and it's causing a divide throughout the tech community over whether the radical new UI is a good idea or not. I've now had that 3 weeks to think carefully about what this all means and how I would write about Windows 8 in a unique way (there's plenty of articles on the web showing demos of the new Start Screen). I had originally planned to write 2 articles, one about Windows 8 and the other one about user interface design (more specifically the Metro design), but I'm going to combine them into this one article, because I think that it's hard to talk about them separately anymore considering we know what Microsoft's plans are in the future regarding the UI for their products. It's an exciting time, but you really need to understand the key principles behind what's going on before you can truly appreciate what's going on. When I first saw what Microsoft planned to do in Windows 8, I was quite shocked, but after a while, it just clicked. I now have a good understanding of what Microsoft's strategy for the future is (and it revolves around Windows, Office, Skype & Xbox although this article will mainly focus on Windows) and I'm hoping after reading this, their strategy finally just clicks for you too.
