The problem is that now one else is currently making hardware that is competitive with apple silicone. Apple is the only one offering both performance and battery time.
I love my Thinkpads, I really do but they are bulky, loud and the battery doesn't last very long. They are not an option for many people.
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.
Intel lunar lake gen 1 and 3 are competitive with the M series both in battery life and performance. Qualcomm makes arm chips that are somewhat competitive too, but you run into similar problems as M. x86 chips can most definitely reach the efficiency of M.
