I think your point about a "killer app" has some merit. I've certainly found no reason to stay in Metro so far. However, I just can't see where the value is going to come from. Metro is neat looking, but I just can't think of anything that could be done in Metro, while maintaining the "look and feel" (and the tablet-accessibility) of the interface, that wouldn't be better as a web app. Sure, you might have a Metro skin that dumps you into the desktop to do complex tasks, but then there's no real value in the Metro component. Take a look at the Metro-based ERP app "concept" MS has apparently demonstrated: http://www.zdnet.com/blog/microsoft/microsoft-shows-off-windows-8-business-app-concepts/12189 http://www.zdnet.com/blog/microsoft/microsoft-shows-off-wind.... Literally everything about it looks like a (reasonably sexy) web app. Plus, it's an ERP, so there shouldn't be anything running locally, or very little. This is basically just a platform-dependent web application. In some ways, it even smacks of Active Desktop all over again. Aside from extremely loyal, MS-only shops (of which, I admit there are probably quite a few), I just can't see anyone using something like this for anything important enough to reach "killer app" status...
