0. Linux support, specifically with the option to purchase without paying the Windows tax for an OS I'll never boot. This is a deal-breaker for me, meaning Dell are one of the few main-stream manufacturers I'd go with.

1. No touchscreen (I'd rather have a higher quality, low glare non-touch display).

That's about it, actually. Practically all modern laptops seem to meet my expectations on battery life and performance in a way which corresponds well with their cost. Weight is mostly a non-issue since I'd only consider a 13" chassis anyway. Screen resolution can be traded for battery life without concerning me.

An M1 Mac with a non-apple keyboard and full Linux support would probably be great, but I don't hold out any hope for another manufacturer matching the M1 without ruining it somehow (looking at you, Chromebooks).
