I completely agree that would be awesome to have windowed metro apps for us desktop users, but at the same time I doubt it is going to happen. There was not a single desktop on display during the show. The closest thing was the 27" all-in-one, or maybe the xbox. MS is sure that the desktop form factor is going to be dead soon for consumer use, and so they are moving the bulk of their focus away from innovating new features for the desktop without killing it off.
There were a lot of things I did like though; Native 3D printing support is neat (will be getting my first 3D printer either Christmas or next summer), more resize options for metro apps is neat, giving developers better tools to make useful metro apps is neat. Lots of little neat additions and tweaks... but no major 'wow' features.
I was hoping for more cross platform capabilities between WP, win8.1, and XBO. It looks like they are headed that direction with the addition of speech for win8, and better unifying the layout across devices... but it is still not what I was hoping for yet.
And what where they thinking with the typing on the 8" tablets!?!?!? WP8 has a perfectly functional system where the word predictor sits right above the keyboard. It is easy to access, is extremely good at predicting words, and works like a charm. All that they had to do was use the same thing on the small tablets. BUT NOOOOOOO, they had to break something that works well and add some silly space-bar gesture thing. I do like the new way of entering punctuation, and I hope that finds it's way to WP with an update, but that space gesture thing is needlessly complicating a very simple task.
