Consider that iPhone OS (when it was unveiled in 2007) neither looks nor acts like any desktop OS, and yet it still succeeded. Apple didn't have to put iOS UI on the desktops of "a billion people" in order to convince them to buy an iPhone. If Microsoft has to do that to get WP7 selling, then I argue that Metro is already a failure: it isn't compelling enough to make people switch to WP7. That's not my opinion, but rather my reasoning, which you are welcome to point out the flaws in, if you think I don't get it.
iOS didn't have to go on a desktop but iOS's home screen is the same as the menu on every popular phone for the 4 years before it, with the only difference that you touch the icons rather than select them with buttons.
The most common comment against WP7 I've seen in this discussion is that WP7's home screen has big ugly buttons. But I think that's more because people arn't used to information being on the home screen icon rather than just in the app. If the buttons were any smaller you wouldn't be able to read them! For instance I have a WP7 phone and currently my home screen tells me, calander appointments for today and tomorrow, the weather, current stock prices for BP and percentage change, number of new artices in my RSS app, latest headline from the technology section of the guardian, latest headline from bbc news and how many new emails I have.
Once people are used to having live tiles on there PC, there's a good chance rather than seeing big ugly buttons on WP7 they'll understand what they are.
