200g is weight of a smartphone, there's no way touch weighs that much.
Framework 13 Pro screen seems to have plastic surface as before, not glass-laminated (which I guess could add 200g, but it's not a requirement for laptop touchscreen)
I’ve literally never used the touchscreen.
You're blaming the touchscreen for a lot here, when the explanation is likely a lot more pedestrian. Change in case molding, change in PCB size, slight change in battery size...
e.g. 30g in larger heatsinks, 80g in glass-laminated screen, 20g in larger battery, 40g in more stiffer chassis. 30g in aluminium top case instead of carbon fiber :)
Maybe that's the reason, not the touchscreen?
I don’t buy it.
Weird.
A bigger battery is the more likely cause.
But I wouldn't pay (much) extra for it.
