I'd like a 950XL to replace my excellent 1520 because I want to keep the photo quality I get with Rich Capture, I want to keep having a large screen phone, I want to keep Cortana, I want to keep getting upgrades for the OS, I want the freedom to play my own media files, I want to keep offline Here Maps, I want to keep Live Tiles, I want to keep the excellent MicroSD card support, I want to keep the way I do things, but I'd also like something new and shiny.
