Do you mean recycled aluminium is softer than "new" aluminium?However, the recycled-aluminium that they have been using has not been the hardest material out there, and is subject to dent / chip upon normal daily life abuse.
My old Air is 9 years old and looks like new, I was never that careful with it - it got thrown in a bag.
The new Air seems just as well built, if not better. I have no worries at all about it not being durable - more so as there isn't even a moving fan - 0 moving parts.
It is durable in the sense that it is more or less a slab of metal without points of weaknesses. However, the recycled-aluminium that they have been using has not been the hardest material out there, and is subject to dent / chip upon normal daily life abuse. But you can say such damages are just cosmetic, the actual structure is pretty sound, the hinge and keyboard are sturdy as bricks.
I happen to have used a 2018 13" Pro prior to replacing it with the M1 Air as a daily carry machine. While this is nothing scientific, I do feel that the material in the Pro is slightly harder, or that the corners and edges of it feel less prone to shape-changing damages. I do not abuse my machines but I also don't babysit them either, your milage may vary, but overall it seems it is true that the higher tier models tend to equip with better structures and/or material. My father uses a 16" and it feels like it is indestructible unless dropped.Do you mean recycled aluminium is softer than "new" aluminium?
From specifications it looks that MBA is using recycled aluminium but MBP is "new" aluminium. I have been always wondering if there should be any meaningful difference between the two in this regard because from my understanding/assuming they are using the carvings/shavings left from their own production rather than old beer cans and such...? I mean does it really matter if they just melt again shavings left our from MBP casing? Of course if they mean they just mix together all different series aluminum they use, I guess it is not so good then?
Does anyone know this and especially durability and hardness between recycled and new aluminium?
Too soon to tell if the M1 is pretty durable. We will know in a couple of years.right now im treating it very very kindly
I also had MBP 13" 2019 before I got my MBA M1 but I'm still not sure about whether this is due to difference between recycled vs new aluminium hardness(?). IMHO MBA feels in many ways much more solid than MBP did probably due to "tighter" packed internals in MBA (so MBA does not have hollow sounding trackpad and keyboard, and also knocking the bottom case in different locations sounds much more solid in MBA compared to MBP). Also I could not tell any difference between display lids, they both feel equally solid to me when slightly pressing or twisting them (is it actually identical / interchangeable part between MBA and MBP besides the LCD-panel itself?). Most difference IMHO is in the bottom part while MBA more solid, it is also more flexible especially towards front but I think it could be mostly due to wedge shape, so slimmer and much more round shaped bottom part of the front makes is more vulnerable.I happen to have used a 2018 13" Pro prior to replacing it with the M1 Air as a daily carry machine.

But how many hours you actually used the machine during that (not 72 hours I think)? I mean my point here is that I could have 3-4 weeks between charges with my MBP 13" 2019 if I did not use it much...charged the battery that night and again on Sunday night, and then used it from Monday thru yesterday without charging it and it still had 40% battery remaining....
The top lid is thin and the display glass is right underneath. A sharp impact to the top outer case could crack the glass. But this is not unique to the MacBook -- any thin laptop can suffer the same fate. If you're not going to baby it, consider a hardshell case or transport it in a padded case.I don't care about cosmetics. a scratch here or there I'm ok with .I just don't want the screen to crack. im babying this thing. as said before I grew up very poor. so I tend to worry a bit more about my stuff id be so sad if I broke this wonderful laptop
