Courier looked extremely promising and I'm saying that as an OSX,iPhone,iPad user. How they could kill that thing off still blows my mind. Then again we have only ever seen an interface mockup, haven't we? Maybe the software / device they had didn't work. Still no excuse to just let this idea go, I still think that a booklet style tablet with pen, capacitive touchscreen and these GUI ideas would be great for many usecases. What's MS's thought process here? "Yeah no, we don't think specialized solutions like these are great for us, let's instead keep smashing on Win32 until it fits unto smartphones and tablets and serve one huge shit sausage."
I wait with pleasure for the business user reactions once Windows' most useful and perfected feature, the start menu, is gone and replaced with a touch optimized fullscreen window with gigantic whitespaces and huge mouse paths for achieving anything. It is going to be beautiful.
