With the end of working in offices. I tend to work in coffee shops and I have a tablet that I bring as a second screen.
One thing that this working situation changes is that I carry my work laptop around. I kind of want to avoid being "at work all of the time" so it might be nice using a computer that isn't my work laptop but that starts to mean carrying around a lot of stuff.
One idea that came to mind is that maybe I could use something like a raspberry pi and use my tablets as a monitor (like I already do to get a second desktop monitor). There are quite a few "mini computers" - but after considering this for a second (and looking at some hardware) I realized that a lot of these mini computers didn't come with a monitor.
So this made me think - is there a compact way to use a raspberry pi without a power supply. Are there other computers with a similar form factor? Could I use an external usb battery like I can for my phone? Is this all a silly idea?
