Microsoft is really good at creating concepts, unfortunately the implementations always seem to lag behind (think of the Surface and the Origami project).
I could see myself using something like this, a device that is always with me, where I can sketch, compose and browse, fold it and throw into my bag. Can I do all of this with a combination of iPhone and netbook? You can, but sketching on an iPhone is kind of challenge, and netbooks aren’t really my cup of tea, there’s something about the size constrictions that make it really discomfortable for me. Plus. why do need a keyboard on a tiny device, a virtual keyboard is all I need, writing with a stylus is questionable, but it usefull for sketching.
Bring it on Microsoft, don’t let us down.
