Recently, I've had a couple of friends reach out to me to have me shop for MacBook Airs from the M3 and M4 eras. At first their preferences of 15-inch vs. 13-inch were ambivalent, though leaning 13-inch. This had me looking for each, albeit separately. Long story short, I've noticed a trend and I'm curious if others have noticed it as well and/or if there is a likely corollary or explanation for it.

The trend:

There are more 15-inch MacBook Air configurations than 13-inch MacBook Air configurations available at any one time on Apple's "Apple Certified Refurbished Mac" section of their online store. There are also more 15-inch MacBook Airs (than 13-inch MacBook Airs) with higher-end storage and RAM configurations and configurations, let alone CTO/BTO models in general.

My theories:

Best I can think of is that, on average, those buying the 13-inch MacBook Air generally don't care about custom configuring it for higher-end RAM and/or storage and are plenty fine with standard configurations (for whatever reasons) and that those buying the 15-inch MacBook Air are more deliberately looking to spec it out.

I'm also basing a lot of that on the theory that availability of Apple Certified Refurbished MacBook Airs in a given configuration would preclude that a certain number of those configurations were made and/or sold new at some point as well as a similar "they have to have been purchased new to appear used on eBay unless having fallen off a truck" theory.

While, I'm guessing that most of the folks that buy 13-inch MacBook Airs are also the same folks that have been buying 13-inch MacBook Airs for the last 15 years. Maybe you have folks lured in by the M1 MacBook Air. Either way, they are the same class/type of user that has generally been buying 13-inch MacBook Airs. I'm not entirely sure which crowd is buying the 15-inch MacBook Air and what their priorities are (on average).

Anyone else have any insight on what's causing this trend or any of the other nuances therein that I may have missed? I find it sort of fascinating!
 
I suppose if someone is willing to pay for a custom configuration, it’s “likely” they’d pay extra for 15” too.

Or, maybe, the refurb custom 13” are just more popular and sell out quicker.

Are you using refurb-tracker.com? It will let you know when a certain configuration becomes available; even if you still miss it you’ll be aware that it was there.

I use refurb.me. Admittedly, I don't look at their statistics and I probably ought to if I'm even this curious about it.

Otherwise, I think 13" models are probably more popular (and I cannot fathom that there are many that would jump at the chance of a decent custom 13" spec [hell, I got a pretty decent refurb M4 13-inch model that had 24GB of RAM and 512GB SSD for only $320 more than the 512GB MacBook Neo!]). Still though, it's interesting that it seems much more common for folks to be buying higher specs on a 15-inch Air compared to a 13-inch Air.
 
If you're in the US at least I have to vouch for Amazon preowned (sold directly by Amazon).

My 13" MBA M5 (24gb/1tb) was sold as "used like new" and arrived literally sealed brand new.

$1499 MSRP for $1230.

And even the new pricing on resellers is outstanding and beats Apple EDU pricing.
($1349 vs $1399 right now)

Not sure that's entirely relevant, but still good info!

Cough cough 😷 Best Buy returns. I bought my MacBook Air 15 I saved 300 off of it. I also bought rog ally x 200 off. It’s a great deal. They look brand new.

Anyway I think you are on to it. People buying the 13 may just want the cheapest and those who buy the 15 are willing to upgrade and spend more.

Aka people spending their wallets on the 15 vs the 13.
