There should be a product that you can buy (a computer) that you bring home, plug in, set up via your phone or computer that:
- can host websites
- can store your files and sync them to other devices
- control your home automation
- host your email
- anything else you might otherwise put on a server
And does it all EASILY with a simple phone or web UI.
Yes I know you can actually buy a computer or server or raspberry pi and put something like NextCloud or Home Assistant et al. on it, but the real barrier imo is the setup and configuration. Even I don't do all this because it seems daunting to configure all of it, and I consider myself a pretty technical person. I really just want to buy a box, plug it in, and like select which apps I want to use, and then it starts working for me.
