I realize this is heavily personal preference but every laptop touchpad I’ve ever encountered is absolute garbage when it comes to accidental touch detection. I would love to see a 10-key sized touchpad that could be placed on the either side of the keyboard. Whether this comes as a module made by framework or a 3rd party vendor, this would be an unbelievable boost to device usability.
At least with the 16 I’ll be able to remove the trackpad entirely. So that’s already a strong plus.
