It was mostly meant as a tongue-in-cheek comment, but I wanted to point out that the goalposts are moving and if they move faster than the pace of HW development then people will be disappointed.

The biggest challenge is probably the "modern web", which is frankly a pile of s#!t and shows no signs of getting any better.

For this project, the ability to run a full linux desktop version of firefox should mitigate that concern, because then you can use extensions like ublock origin / umatrix and cut out a lot of the bloat (which tends to be for tracking/advertising and not the functional stuff you actually want) by blocking it.
