I always ask about battery consumption... Apple seems to be on another galaxy right now. I decided to stop waiting and installed Parallels to run Ubuntu there... I really wish the best for Asahi Linux.
Do you need to be in that galaxy? I easily get 8h with this $1400 64GB RAM AMD Thinkpad with an OLED screen running unoptimized Ubuntu (yes it looks 90s anonymous). An equivalent notebook for most practical purposes from Apple would be at least 3.5× more expensive.
