Arm based rival to your x86 home pc?

Background: It appears Apple are switching processors yet again from X86 to Arm, which seems to be a vote of confidence in Arm. I hardly expect Apple CPUs or SBCs to come on the market. But Apple obviously sees the potential in Arm.

Question: Now the software is there to run linux on Arm, but is the hardware? What's the best offering? Is it the RazPi 4?
