That touchpad is tiny so I'm not sure how useful it will be (probably just for cursor usage on desktop). Good to see 120hz and hopefully with VRR support.
Seems that ootb Linux support is a few months after initial release.
I've never seen the Legion Go irl but the old one looked like the touchpad was just the right size too be unobtrusive but still practical. The new one looks like a thumb print reader.
