It doesn’t really take all that much to run 2Gb speeds if you’re not doing much with the traffic - any modernish processor in a small fanless box would work with 4-8GB ram. If you’re wanting to run Suricata, VPN, etc then you need more.

Regardless of whether Memmy is the most “iOS” like, it’s the most like Apollo (RIP). I do like Avelon and Voyager as well but Memmy is my favorite and just feels compact, clean, and right.
