Just wondering what Windows 10 Mobile is like on the Nokia Lumia 635. Detailed reports would be great. It's for my little sister's phone. She thinks she's getting a new phone for Christmas (she wants a Samsung Galaxy or an iPhone...of course) and I want to inject some new life into her Lumia 635. She thinks she hates Windows Phone even though she's never actually used anything else and barely knows how to use Windows Phone despite my attempts to teach her.
