I will be actually, I was pretty interested in the M2 Pro, I am currently very satisfied with my M1/8/512 Air. While I am not the target market for a base model and would go for at least a 512, the 512 speeds posted from an M2 are still not as fast as my M1. I do move a lot of files around in my hobbyist journeys and SSD speed is important to me, also I hold Macs a long time and since they can't be upgraded its forever. While the SSD may not be that huge a difference today in 5+ years 1200-2000 R/Ws is going look like USB 2 does in 2022. The XPS plus is reported to reach 5000+ by comparison. In the age of PCIe 4.0, it's an arbitrary hinderance to an otherwise very attractive machine that is a deal breaker for me. Maybe its supply chain, maybe is Scrooge McCook or maybe its a design choice, no one except Apple can 100% say why, but it does matter.
I won't be leaving the Apple ecosystem I own 18 Macs, several iPads and iPhones, HomePods, Watches, AirPods... I have all the Apple things...and love each and every one of them, but I don't like this SSD situation and will pass on any future Mac that is ill equipped for 2022.
