I sympathise will all the difficult decisions here, Apple is really blurring the lines now that the SoC is no longer a dealbreaker (for most).
I've yet to decide between the M2 Air and 14 Pro, but I am leaning towards the Air.
I have a wide variety of tasks including photography, education, business admin and client presentations for another business (plenty of hustling!) - all of which are visually demanding. The 14 Pro would appear to make the most sense if only for the display, yet the truth is that I would barely make the SoC sweat. Most of my work is done at a desk at home, meaning I don't really need high specs on the go. Even M1 would be enough.
So, here's 'Apple Knowledge Navigators Bullet-Proof Plan' (patent pending)
I'm (probably) going to order the M2 Air in 8/8 cores with 16/512. Upgrading to 16/512 from the base model rather than the higher model means you save a lot of money from choosing 8 GPU cores rather than 10. With the Edu discount that's 10% off and I'll get the gift card as well.
I'll then order a Studio Display and get the discount for that too in addition to using my gift card, and that display can be my main 'headless iMac' for at home. And if I do get concerned about battery draining or performance in the future, I can hold out for the inevitable 'pro' Mac mini variant.
I think the biggest headache for me is whether the extra £180 is worth it for the 14 Pro upgrades, or whether I'll benefit more from the lightness of the Air. There's also the extra screen real estate that, after comparing in my local Apple Store, is more noticeable than I imagined. Coming from a 13" 2018 Pro, I worked out that the screen is virtually the same size as my current plus the thick black bezel, which is a big improvement.
