One design choice I love here is having the track pad centered on home row, instead of centered on the laptop body. Lenovo has the same orientation. I recently had to switch back to a body centered track pad for work and now I'm aware of the contortions my right hand has to perform in order to type while also resting on the laptop. It slows me down and increases typos. For anyone who types with all 10 fingers, a home row centered track pad is the only serious option.
A well designed trackpad will have virtually flawless palm rejection, which means it shouldn't matter. I'm not sure how that fares outside of Apple machines though.
I have a System76 (not a Lemur, but surely the touchpad software is the same) and I've never once had a problem with palm rejection. For that matter, I never had a problem with palm rejection on any of the Windows laptops I used to use. Are there any laptops that do have problems with palm rejection? AFAICT it seems like a solved problem (unlike, say "smart sleep", which is an unmitigated nightmare everywhere, including on Macs).
