The thing is, Microsoft can integrate with its own products as much as it wants, but I will never have only Microsoft products. If it doesn't integrate well with other products not controlled by Microsoft, I think their strategy will fail. And let's face it, they've got a terrible track record in that area.

Not so along ago (probably still now) Windows had the best software & hardware compatibility. Apart from that, who's going to have an iPad/iPhone and a Windows 8 laptop? Or a Macbook and Windows 8 tablet/phone? At least for the Apple side it's pretty clear to me. Finally, part of what you mention is also developers' responsibility rather than Microsoft itself; as someone says above the company's investing quite a lot in getting developers aboard.
