Technically:

1. Asahi Linux's battery life is like 2/3 as long as on macOS

2. The Thinkpad X1 Carbon is just about as thin and nice as a Mac but it also costs just as much.

3. Apple is still leading in single core CPU speeds but x86 has caught up or surpassed M devices in both multicore and graphics. And even last gen x86 can beat the 3-generations-old M2 that is the latest one supported by Asahi Linux.

Re:3- only because they've only released the base M3 so far- once they release Pro/Max configs they'll easily regain the lead, as seen by the single core dominance.
