I'm gonna be really honest here and say that people have a very distorted subjective idea of what a 'sturdy laptop' is like. A lot of marketing money has been spent to make people think the only way to have a strong object is for it to be made of a rigid metal or glass material, so people go "oh my god the lid can FLEX this thing will break if I drop it!" but that's not at all how things work.

The truth is you can't really just guess at whether a thing will survive falling or whatever by looking at or touching it. The only thing that tells you anything really is actual experience and/or testing.

(personally, I think my framework laptop feels plenty sturdy for all the subjective anecdata that's worth, it's just not designed in a way that's trying to scream at you "you can run it over with a truck and it will work perfectly")
