Yeah most 7" readers have the page turning buttons on the side which usually makes the device too wide for pockets.
The 6" readers fit my pocket quite well… So a foldable dual screen 6" sound like a pretty nice upgrade.
Most of what I use my readers for are reflowable text like epubs… But I guess if you could show a single page from a PDF across both screens then it might actually be big enough to be able to read while still being pocketable… You would probably want to go with the high resolution e-ink screens, like the one in the Kobo Clara HD (1072 x 1448). A combined resolution of two of those would be 2144 x 1448,

I have a Raspberry Pi that runs pihole and Wireguard exclusively. My home server is a Kubernetes cluster running on an old desktop PC and 2 Intel NUCs.
The reason for the separate Pi was essentially because I only had the desktop PC initially, and for a while I had a faulty CPU, making the desktop PC crash or become unresponsive, so it helped a lot having DNS and VPN access separated from the instability.
