>Sigh. 1gbps is widely available, even in relatively poor countries.
No, it isn't. Not even by far.
>And if you're making a _new_ device that should last for 5-10 years, it's just stupid to use technology that is getting obsoleted even now.
Anything higher than 1gbps would ramp up the cost today.

It is. You typically either have only cellular connectivity or you have fiber, with very little in-between. And fiber provides 1/10G capability.
Is it _used_ universally? No. But the capability is there.

This is not going to be a cheap device _anyway_.
