Have an old and very slow Nexus 5 phone. It had wireless charging so I leveraged that and made an (almost)always on nav screen for my car(old honda civic). Have like 10 gb of offline local google maps on it, does very well for is purpose. I also have a very old IBM T42 thinkpad. Very slow, and only really useful as a word processor. I took windows xp off of it and replaced it with KODI, now I play movies on an old tv in my garage via dvd player, usb downloads, and KODI using the laptop. Not particularly fast, but does its job pretty decently for an aged laptop.
