Even around the house it makes a difference in my opinion. My 12” X1 Nano is much nicer to carry and use around the house than my 16” M1 Max MBP is, and so the Macbook spends most of its life docked. The MBP comes with me when I travel because it’s my primary computer, but reduced size and weight would be welcome. If only the 14” MBP didn’t sacrifice cooling capacity as much as it does.
