Finally something that is at least as un bias as possible to do with Win8 with perfectly valid comments portrayed in a clear and un FUD like manor! well done!
Personally having used it quite a lot now, i agree with most of what you say, i find it bizzar that some folk on here seem to pass judgment and sentence after only using it for 5 min, you cant do that and be completely objectionable!
anyhow, from my perspective i see it like this, Metro maintains all the wee things that are usful, it displays a snap shot of important current events that can all be scanned over in a few seconds in a single glance. Using Metro like this (as its intended on Windows phone) is actually very productive, ive been using desktop mode to do all the important stuff, which as some folk seem to have missed, displays windows just fine for multi tasking.
Like the author, my concerns are over the start menu, and icon placment, ie clutter! which ive fed back via the response forms MS have littered about all over the OS which believe it or not were placed there to get your feedback whilst you actually test the thing, like you asked to do in the first place :)
