I daily drive my personal Macbook air M2 running Asahi (only booted into OSX twice in the time I’ve owned it). I really like the experience of Linux (Fedora) on Apple hardware.
However, its still got some growing pains before most folks would be happy with it as their primary. One of those limitations abslutely applies to the Neo. Asahi Linux on 8GB of RAM is VERY cramped. I’ve got 24GB of RAM and even I run into limitations sometimes. The other issue is the current maturity level of power management. Asahi does not have full use of the low standby power states. This means that even with “sleep” your battery will exhaust itself in less than a day if its not plugged in. The alternative is to power down the unit entirely, which works fine to save the battery, but means having to open all your applications back up when you power it back up. Since Mac hardware doesn’t use ACPI, hibernation is also not available, which would also be a fine way to address this.
None of this is criticism agianst the Asahi team. They’ve done AMAZING things so far and what exists today is fully usable to me. Improvements also come early and often. The team is amazing!
However, Macbook Neo probably won’t be a good use case for Asahi Linux for the forseeable future.

Chromebooks with low RAM are fine for many use cases. I’ve got a chromebook with only 4GB of RAM and its perfectly fine for web browsing or watching streaming which is the only things I use it for.
I used to think that too, but then I realized that the way I use computers (and it sounds like you do too) is to keep a unit a long time, take care of it, and use it to its limits (and perhaps beyond). There are millions of users that don’t do what we do. They may be young kids that end up breaking the unit before 2 years pass. They may be a fashionista that has to change out their unit when the new fall color comes out (so they may not even own it a year). They may be an older person that only uses it to check facebook to keep up with their kids.
In all of these cases soldered RAM is just fine because the user will never reach the point they need to upgrade it. What they get in return for this is cost savings and likely a smaller (thinner?) unit, that is probably a bit more structurally sound (because it doesn’t have to have a door or clips to have the RAM sockets accessible.
For users like you and me, soldered RAM is a bad thing. For most common users they don’t care. They don’t even know what soldered RAM is.
