An M4 air will run circles around Lunar Lake being over 30% faster at geekbench (both single and multe-core) and over 40% faster at Cinebench 24. The GPU is 25-35% faster too. Air is also 60-80% faster at Geekbench AI.

People spent a decade upgrading laptops for a mere 5-10% increase in performance (sometimes less). I can't see someone giving up that much of a performance jump unless Windows is absolutely the only option.
