Pretty FOSS?
PC - Thinkpad T14s Gen 4: EndeavourOS, Firefox and Thunderbird with the Proton suite of things such as Mail, Pass and VPN - I do pay for them but I think it's worth it.
Phone - Pixel 8 with GrapheneOS and as many F-Droid apps as possible. Proton apps for Mail, Pass, Drive, VPN. Cromite browser. The only that aren't are probably my banking apps, but I could always switch to web I guess.
I think my biggest hurdle is a Map app that has traffic data that isn't Google maps.
The original large gameboys had a lock that utilized the slot via the power switch. The pocket removed the lock therefore allowing the non slotted Color games to be used in a pocket gameboy.
