I dare say most the concern I'm seeing about this so far is that they've simply not gone far enough... Unless the tiling interface is the primary mode of use, then most people simply won't use it and it'll be relegated to the list of features the OS has, that simply no one uses. I think their intent is that this new UI is the Windows UI. I think they're going to push devs to use this new UI for all apps unless they need to go to the old UI. Recall that native apps will not be cross platform, so there's motivation for devs to target this new UI to run on x86 and all the ARM variants.
