Is there something illegitimate about his questions? Having used or having not used Windows 8 doesn't preclude him from being able to ask these reasonable questions, especially based on everything that we've been told.
From everything that we've been told, the only conclusion that I am able to come up with is that eventually, we will not be able to write our own apps for our own use without a) using a public store, or b) buying an expensive app deployment server. I asked this question in another thread and no one seems to have an answer. All I've seen is "WinRT is for Metro apps", "Metro apps will only be deployable through the app store", and "WinRT is the way Windows apps will be developed in the future." What other conclusion am I or the OP supposed to make?
