Shouldn't ARM-based laptops (Chromebooks, Windows 10 ARM, ...) even be able to undercut this value?
I have no experience with those, and especially software compatibility. I like "the standard" that just works.
Raspberry Pi use ARM CPU, so most stuff that can run on Raspberry Pi should also run on ARM-based laptop. Although i'm assuming those laptop use Linux. And i'd like to mention many chromebook have only 4GB RAM and eMMC storage which is rather slow which isn't much different with Raspberry Pi 4.
