I've developed a Windows 7 app using the Surface SDK for a POS application (ordering drink/food from your table using tactile screen).
I'd like to start migrating to using a Metro App, as I fear the Surface SDK will die soon (and I'd like the app to evolve).
My biggest issue, concerns Windows 8 and how to "lock" it for public usage.
Basically I'd like the machine to boot and run my metro app, and of course prevent the user from accessing the OS using charms or other gestures.
I know how to secure a Windows 7 and older, but somehow the new metro system feels like it's going to be harder to do such a simple task.
