My question is this: what would you plug into POE that would need 10gbe?

Ubiquiti sells Wi-Fi access points with 10GbE uplink ports that are PoE powered: https://store.ui.com/us/en/category/all-wifi/products/e7

In theory at peak throughput the access point might use close to 10 gigabit. But definitely more than 1G/2.5G.

I had no idea it could supply 90 watts or so. At that point you could power some pretty powerful terminals.

The new 14” MacBook Pro comes with a 70 watt charger. An M4 Air only gets a 35 watt adapter.

Basically seems like enough power is available to run something pretty powerful.

It's really ~71 watts on the device end (not counting any inefficiencies in the device itself). Still plenty powerful to do a lot with, but also more limiting. Especially if you don't already plan on having a built in battery to handle bursty workloads for whatever reason the device needed a 10G port for.

With most day to day things being some form of streaming it really hides how painfully slow gigabit is.

Additionally, it's not difficult to fit 10gigabit worth of data munging in a 10-15watt envelope.

Pulling data off of modern professional cameras is an easy example.

Realtek's latest NIC is 10/100/1000/2.5/5/10, has a <2w envelope and has offloading that works (unlike intel).

What if you need a small switch somewhere due to the runs otherwise being too long?

A multi-radio WiFi 8 AP?

You would likely need fiber to saturate it...

I have a WiFi 6 AP that can saturate a 2.5GB link when I test it with two devices. So far, for me the peak speed for an individual device was around 1.6GB

I have not yet tested WiFi 7 APs, but they are supposed to be even faster. The use-case for me is video editing over WiFi (I do have a 10GBe Thunderbolt adapter but hey, I like wireless).

an all nand-flash NAS ?

Another smaller switch closer to the location of your devices.
