I've got a Surface Pro 4, with a fingerprint ID type cover, and of course the SPro 4 stylus. I've been toying with the idea of upgrading to a Surface Pro 7. Since the type cover and stylus are extra-cost accessories, I'm wondering if I really need to buy them again. Would my existing accessories work with the 7? I gather the newer type cover has magnets to turn the Pro 7 on / off much like the typical iPad cover, and the older cover won't have that, but at least I'd get to keep the fingerprint sensor. I've found face ID to be a bit slow and sometimes unreliable. I'd also welcome any comments from people who have gone the Surface Pro 4 -> 7 upgrade route. I gather resume is a lot faster now, for example.
