Metro is a great interface. For Tablets, Phones, and even Laptops. Desktop is a bit iffy, but I like it. That's why Microsoft is testing it still. I, in my humble opinion, Believe that Metro represents a step forward into clean, easier to use, interface that is fluent on multiple devices. Including the desktop. I like using the Metro on my desktop, as it provides a great way to get information faster. With the tiles, you can easily view incoming data, or click it once to open up fast and fluent. It "Just works" great. Now all this is my opinion. But let's take a good look at WIMP. Its a great, tried-and-true paradigm. But if WIMP/GUI never challenged CLI, the world would be a much different place. It's new, but let's give it a chance. WIMP wasn't perfect when it first came out. It needed tweaks, and fixes and overhauls to get it right. So, I say let's give it a fair chance and stop the bickering here. Microsoft, for the first time in a long time, has actually brought something brand new to the table. Its a first try, and remember this is a beta.
