Why would you need Pi images?
Discussion
If you don't know about Pi images, then you have no need for them
If a product only supplies a Pi image, it's suspect.
Everything that runs on a Pi can run on another Arm SBC, but better.
Ok
16GB look good. I wonder how reliable would these be to replace cloud offerings for personal and casual projects like blog, some offline database, wallet, etc
etc.
Instead of paying for providers regularly, you maintain your own infra. I'd assume there will be maintenance costs in time and replacements, backups, tralala
But might be worth it for privacy? and maybe even saving, idnooo
