As much as I'd like to see it, I don't think Windows will ever quite get there. Not, at least, in any recognisable form. They value backwards-compatibility way to much (which is to be commended in some ways, but won't save them here). While they seem to have everything lined up to be able to turn it into something, developers seem too reluctant to get on-board too. Apple will have to go through all of the growing pains Microsoft has already weathered, so they're miles off, but maybe they can do it faster because they don't care as much about what people think of them, and are willing to do whatever they think is right (if it is or not is to be seen). Google is well placed because, while they have a bunch of platforms, the only one in the desktop space is basically dead, and really didn't ever have too much investment in it, so not too many feel put out if they get rid of it. But that not even the case, because they're able to engineer everything so that it stays relevant.
