Re: Interesting.
I/O is always likely to be awkward on a device that size, so I'm used to ignoring it now... and I suppose there are a few boards available now that use the computer-model-4 (CM4) that may provide alternative I/O layouts.
However, I will just mention that having swapped the side where the ethernet jack is on the Pi4 is surprisingly more annoying that I originally expected. I think the (my) problem is that some ports are static, e.g. power, HDMI, ethernet, and things like USB are more likely to be hot-plugged. But with the re-positioned ethernet, the Pi4 puts the USB ports between those static ports.
Might just be me though; I thought I'd get used to this, but, nope!
Otherwise loving my Pi's!!! :D
