The web is a hostile environment. “It is a continuum.” (Jeremy Keith)
Viewport sizes have become fluid, and they don’t need to be the same as the device’s screen size.
Now we need to difference between simple and enhanced use cases.
There are so many input and output methods – and you can’t deduct from the screen size the input method, touch is now everywhere.
2013 60% of the people on the web were on sub-3G (Edge).
In Western Europe, still 60% on 3G, LTE takes a while to come up to speed, especially outside of Europe and the US.
People won’t think they did something wrong when the site doesn’t work because of those blockers.
These factors don’t make our jobs harder, it is our job.
Not just a matter of empathy. Access is our job.
And we – as developers – work under optimal conditions, as we need good connection if we want to work efficiently.
