I just upgraded from an M1 to an M5 a couple days ago.

It is rather shocking how much faster everything feels given I didn't think my old macbook pro was slow. While I expected xcode builds to be faster (and they are), I was a bit shocked when opening a new firefox tab was instantaneous since I hadn't noticed it wasn't before.

Another thing I didn't expect is that the new speakers have noticeably more bass and can get quite a bit louder.

I didn't get the nano-textured display, because having to adjust the display angle to get colors to render correctly is more annoying than having to do it for glare (I don't work in a high-glare environment).
