Battery life isn't a huge concern for me, there are outlets everywhere these days, even on planes, but user-swappable SSD and RAM are absolutely non-negotiable

Battery life isn't a huge concern for me, there are outlets everywhere these days, even on planes, but user-swappable SSD and RAM are absolutely non-negotiable for me, as is the ability to run Linux natively, and actual function keys. Macs are unusable. That said if I'm not doing number crunching I can easily get through 4 hours or more and that's plenty good for my use case.
