I agree! “Edge case thinking” has been the bane of all mobile vs desktop discussions. Mobile has historically been seen as a subset of the real thing. Frankly, much of the UX thinking that has gone into mobile, such as one full screen window at a time is a perfect example of people trying to find that balance, and falling too far into the‘subset’ approach. Of course, a full desktop windowing system on mobile would beoverkill. But now that mobile has carved out it’s own space, it’s time for it to grow out of this subset mentality and first admit, then second solve, these higher order issues.
