I've seen a handful of sideloadable apps for iOS/tvOS which depend on alt-store. I'd like to try them out but it's a shame you need a Mac or Windows PC in order to run the server.
I have a MacBook but it's a work machine so probably best to avoid running alt-server there.
The only other computers I have for personal use are a Linux laptop and a Raspberry Pi.
I understand why (iTunes is a requirement and not available on Linux), but it's a shame. Maybe I could run Windows in a VM and run it there, but my gut-feeling is that it won't be that straightforward. Plus, I'd need to start the VM once a week or whatever to re-sign the certificates which would get annoying.
While I am mostly comfortable with the convenience of the App Store, it would be nice to be able to sideload on apple operating systems other than macOS.
