Even if you disable the 'metro' interface it still looks clunky and not very intuative. The taskbar looks like it is too thick, but that is probably something to do with the laptop screen I am using it on. If you are the average user it is unlikely that you would know how to 'fix' these things, and with registry editing, there is always the chance that a novice will kill Windows.
This isn't really a review of the OS, this is mainly me just venting my feelings after I have had my first major session using it, I certainly wouldn't recomend upgrading to it (if you can even call it an upgrade...) and I won't be upgrading anytime soon. I also will avoid using the metro interface at all costs, thanks Classic Shell! <3
