> two generations apart
replyYou'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...

replyIf they're two generations apart, then 200g difference could be hiding anywhere, but touchscreen (I really doubt it adds even 20g).
replye.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 :)
> two generations apart
replyMaybe that's the reason, not the touchscreen?
Wait, so they get _heavier_ each generation?
replyI don’t buy it.
So you'd rather buy the far-fetched conclusion that it's the touch screens fault?
replyWeird.
A bigger battery is the more likely cause.
