Still the biggest advantage x86 has over ARM in my opinion. I hope one day common ARM processors become as flexible.
Either way its amazing to see x86 processors so cheap, low power, and still rather powerful. I hope to see more devices using these N100's
I asked Raspberry Pi about the likelihood of seeing UEFI support this year and it didn't sound like it was a priority, at least not for the Pi 5 generation. Would still love to see it, as it would let distro maintainers focus less on a few "premiere" Arm boards and be able to just have one distro for aarch64.
I recently got a Raspberry Pi 5 and regret not getting one of these N100s instead for a small home server. A lot of the killer features of the Pi like using a traditional phone charger, being passively cooled, and being "cheap" are no longer there if you want a stable system. On the other hand, the "low power" from ARM systems, it's not that big of a lip compared to a traditional X64 mini-PC CPUs.
Things were really different at the time of their introduction. There wasn't really anything similar except the Marvell based sheevaplug.
The only thing I'd use a pi for now is something that really needs GPIO as well as significant processing (eg more than an esp32 offers).
I've moved on to N100s for most of the low-cost stuff but RPi HATs and the GPIO stuff give it pretty good future value for awhile, I think.
I have 2 Rockpro64s which I boot and installed the default ISO of Fedora Server from an ISO file on USB.
