Perhaps the word surprise was too strong, I expected it to be heavier, but I did expect that it overall it would have the same thin and light feeling as the 13 inch, which it does not.
I suppose what is the most unexpected, is how dense the 15 inch feels. It’s as if it’s carved directly out of a solid block of aluminum, where is the 13 inch feels like it’s hollowed out of a block of aluminum. Apple has gone on record, saying that they had to add extra strengthening to the 15 inch MacBook Air, and it is correspondingly heavier as a result.
Now to everyone who’s laughing at this thread, I think the point that OP is making is that this laptop has the moniker “air“ which set an expectation that this thing is going to weigh nothing. When I handed a good friend of mine, my 13 inch M2 air, his first comment was “why does it feel so heavy?!” Apple’s marketing has people thinking that this computer weighs nothing at all.
