You don't notice you're on ARM at all. Everything "Just Works."

And you're seeing 20+ hours battery under normal workloads (i.e. not spec sheet "20 hours" but day-to-day). I've been mainlining a Windows ARM laptop for six months, and am yet to run into anything I couldn't do.

I run WoA on my daily work laptop and everything I run other than some of the junky IT-pushed apps (outlook extension to report phishing, etc.) are ARM64-native and run as expected.
