You can pay monthly for an indefinite apple care warranty. Kinda nice when the soldered on components die they’ll replace it.
I think the M3 stock outpaces the M1 Pro. Edit: seems to be a toss up. https://nanoreview.net/en/cpu-compare/apple-m3-vs-apple-m1-p...
I think the GPU performance is better for M1 Pro. M3 has better single core performance and a slightly better power efficiency. I don't need single core performance though as I don't do things that need burst performance on a single core. And for battery power, I think any Macbook is way beyond my needs at this point.
Also similar spec'ed Macbook Pro 14 with M3 (non-pro) is above $1900 after tax. Almost 40% more expensive. Not worth it IMHO.
Its charge cycle count was 2 and the machine itself is in excellent condition. I think M1 Pro processor is way more capable processor than M3 (non-pro). I know it is 2 year old but Macs go a long way. I'll switch to a newer laptop way before its support will end. So far I'm happy with the purchase.
