Yea Metro is pretty useless in its current state. This is a full PC yet metro apps are so limited and stupid.
There is not one app that approaches the same functionality as desktop apps except for stupid apps. Even OneNote the flagship app is missing most of the functionality of the desktop app.
So yes it is a failure that's why Ballmer and a lot of others are no longer there.
Will they fix it in 9 who knows but possibly, by putting the start menu back and defaulting to the desktop
I agree with the features. The desktop version of OneNote allows you so much more functionality than the Metro version, but how do you condense it all into Metro? That's the challenge, and I hope they can figure it out.
OneNote 2013 is very touch friendly though, they could just put that into Metro really.
