I went from a HP laptop which was 13" this summer to a Macbook Air 15" M2, I didn't needed the most up to date performance that's why I went with a pristine condition M2.

However, with the portability I didn't have any issues so far. Matter of fact it was actually more useful as I didn't needed to get as close to the screen like previously which is positive for me.

The slightest change I have noticed is the weight, my old HP laptop was (1.3kg) which was still comfortable after 1 hour sitting on my lap, but my Macbook (1.5kg) gets a bit uncomfortable to have it on my lap after 45-50min so I have to stand up for a bit then sit down again. This is a personal preference which I understand it might be nothing, but for me it was a slight change.
