Your app should always assume both, touch and mouse input. Any of those can appear (and disappear) at any point. Additionally, your app should scale nicely across different screen/window sizes. That said, there might be some rare cases where you need info on the currently connected input devices. We're working on an API for that [1] which I think Timo is already looking to add to the images, but it's not landed yet. In any case, if you want to know if you are "on a phone or on a desktop", you are probably trying to walk the wrong direction.
