I've been using windows 8 and surface for a few weeks now and i have to say its a great move. I know people keep bagging it but its does work very nicely. Love how its fast and responsive. Since the patch last week on the Surface its runs even smoother and apps load faster. For a first try this is a fantastic device and is on par with whats out now.
Apps are not all available right now but i do see it growing slowing and it will over time. People just need to get over this fear stage they seem to be in. MS are changed the because they needed to, tablets and phones are the future. With saying that i love my PC and will never give it up :)
