obviously it's just my thought, I see people in this forum who are limited by the lack of USB ports to expand the root partition, or would like to connect an SSD or a harddisk (from my point of view making careful purchases is better than buying the essential minimum)
then obviously the aspect of economy also comes into play,
if I need to buy 3 or more to bring wifi to a large house, etc
Ceiling/wall mount and/or PoE powered? Find a used business-class AP (TP-Link Omada, Extreme Networks ...), they can often be found in the €20,- range.
it seems the "untold" of the discussion is that "dedicated APs" do not exist, it's all about routers.
I'm abandoning my R7800 for a x86 based router (and virtualization and bla bla bla), and it seems i'll have to keep the 7800 for AP functionalities (and switch)..
They do, but at least in the past, the economy of scale strongly favoured wifi routers, they brought better features (even today, many APs are still 2x2 and/ or DBDC, while the better routers come with two dedicated 4x4 (or 8x8) radios) for less money. APs were mostly a business thing - and priced accordingly (and in used condition, they were usually too old to be worth it).
