I have already answered. I said it was a masterpiece IMO. If you fail to see that, then you obviously have a totally different opinion of what a mobile phone masterpiece should be. So there really is no point in exchanging views because your views are so different that they are irrelevant. That's it really.
It does what I want a phone to do, but does so prettier, nicer, and faster. For many like me, it really doesn't need more than that. In the future I might have to consider a WP7 instead (which may very likely have incorporated many of the innovations of the N9 by then), but that future is not now. What I know is that the N9 will be a good companion to me for the foreseeable future, and everything after that is unforeseeable by definition.
Take your Magenta N9 down town next week to a strategic hipster coffee spot and swipe your open apps / icons / etc mindlessly into infinity with your gaze focused on a far horizon and enjoy your RAM upgrade...
