This is about snappiness only, I have no trouble finding workloads stressing this old i5 (e.g. 2k/4k videos), where an M1 would fly through. Personally, I just think snappiness alone is a bit forced argument to spent 2k$.
When this is your main tool, it’s much more pleasant to use something with a nice build quality.
I guess different people just have different needs. ¯\_(ツ)_/¯
Tho, I suspect it will perform much, much better cleaned, repaired and thermal-paste reapplied. But I wont open it, as long as I have no alternative set up.
(Also M1 + Linux, would be a no-brainer for me - best bang for the buck right now. I just fucking hate Apple OSs and the ecosystem. Oh and the keyboard too - feels as pleasant an ATM's number pad... Following Asahi closely, still.)
I try the Macbooks' keyboards every time I see one in the store. Yes, it has been even worse, but the new ones feel clickity-clackity, like an ATM pad, to me too. No travel, and annoying high pitched noises. Feels weird to rest your fingers on those keys. Not even close to a Thinkpad keyboard, old or new. I could get used to it, but it is not a great input device. Not at all. Trackpad rocks of course, but so does the nipple, if you type a lot.
