So you're still in the return period? And I'm guessing you're considering M2 Air and have M1 Air?
If you're in the return period, it's just really up to you whether MagSafe, ~20% faster processor, 35% faster GPU, new design, better speakers, faster WiFi, better camera, and brighter display is worth $300. It sounds like the M1 is working fine for you now, so it's just whether you're going to regret not having these new features.
One thing to consider is it seems like the new M2 Air will be in high demand, and MacBook Pros have been backordered for months with 4-8 week delivery times, especially custom orders. So, it might take you a while to get the new Air unless Apple has figured something out that they haven't with the MacBook Pro.
Also, I'm going on a rant here, but please, I beg of everyone on this forum, stop all this nonsense of "futureproofing." You can't futureproof a device and the economics of it almost never work out. I thought I was futureproofing when I bought my 2018 15" MacBook Pro and the processor was 6-core after years of the maximum processors being quad-core. Then, the next year, the processors were 8-core already. Then, the next year, the first Apple Silicon computers were shipped and the "measly" base M1 processor was more powerful, more efficient, and ran at cool temperatures at $999 (MacBook Air) than the most powerful 2019 MacBook Pros that capped out at over $6,000, were battery hogs, and had thermal issues. You will save a lot more money, be able to enjoy new tech more often, and overall likely have less tech issues/annoyances if you buy lower-specced devices and replace them every 3-4 years rather than buying maxed out, higher margin devices and replacing them every 6-10 years.
- $1,299 Base MacBook Pro / 4 years = $325/year
- $3,000 Higher-Specced MacBook Pro / 8 years = $375/year
And SoCs aren't the only thing that become outdated over time when trying to futureproof. You have to think of RAM being enough, having enough storage with increasingly larger files, WiFi generations, screen technology, general reliability of the device which will decrease over time, battery life and replacements, evolving I/O (HDMI, USB, SD Card), etc. Why try to drag out a device that will be quickly outpaced by newer devices, likely cause more headaches, and won't even save you that much money or any money at all? Get what you think you will need for the next few years.
