Interesting... how does Banana Pi Pro compare to Pi4? e.g., performance, interfaces/ports, price, support... How compatible (if at all) is it with Raspberry Pi? How strong is the user community? Basically, I am looking for a low power, (relatively) cheap, (relatively) high performance plug-type computer to run things like mythfrontend, backuppc, or any other projects that I have that require less than a full PC and more than an Arduino :) Also, want to make sure it has good support so that the platform will be around for a while and I don't have to start again if it gets abandoned. > How does 4.x compare with 3.x in terms of CPU and memory usage?
