Having at least 1x1 802.11ac that's capable of working in the 5050 to 5900 MHz band will be a huge feature improvement. Such as to connect to a 'modern' AP running in an 80 MHz channel.
There's tons of environments where 2.4 GHz is a CSMA hell of noise and the performance in a single 20 MHz channel will always be crap, and ranges/real world distances between AP and pi will be very limited because of the extreme noise in the 2.4 band.
It's one of the few products I look at with awe and which makes me feel good about the tech industry.
I managed to build a WiFi temperature sensor (which can be substituted with any analog sensor) which streams its data to a web platform (I also built), encrypted over HTTPS (with CA certificate verification), using a $10 Raspberry PI Pico W; built in a single weekend. I can connect it to my phone's WiFi hotspot from anywhere and stream data to my web platform where it displays a realtime chart. $10.
The Pi5 is even slower than N100 cpu, which is low power mobile laptop cpu.
I remember programming ATMEL ATMEGA8s and being amazed as how much I could do with them, so to me, the fact that devices of that size can approach even half the clock speed of a cutting-edge computer, and have multiple cores, is mind-blowing.
