WINDOWS PHONE 7 USERS: How is the OS?

I am thinking about switching to Windows Phone and I want to know from actual users how the experience is? Do you like it? How is it when compared to the iPhone or Android? Any noticeable missing features (Besides the ones the are coming in the update Mango)? Thanks.|||And what exactly would 'noticeable missing features' be to you? The Windows Phone 7 is a wonderful %26amp; unique OS even as it is now (most users will tell you that)...and it only gets a whole lot better (and faster) with Mango. If you are interested in finding out how the OS works, you can always check out the videos on Youtube.|||When we first covered the OS in full, there were two omissions that we felt were troubling, but at least one of those has a fix coming soon. As you've probably heard, the devices won't support copy and paste out of the box, and won't support third-party multitasking of apps. The former will be eradicated in the form of a software update coming in "early 2011" according to Microsoft, and we've actually seen the copy and paste function demoed by company reps, so it's definitely close. That's great news, though it would have been nice to see it on board to begin with.
