there's an interesting discussion to be had here around desktop vs mobile applications/UIs. Despite the promise of the existence of a unifying paradigm I find that often technology providers pick a preference or a preference bleeds through culture (more of our QAs use this device) or by pandering to the majority user (typically phones today). In our case I imagine the culture of traditionally accessing HN through an IDE-capable device results in the default being optimised for desktop use.
Spotify recently (well over a year ago now) merged its two clients with the mobile UI being the winner. Its interesting how as a desktop user you notice all these imperfections where you are now the loser. The search is top(ish) left instead of top right and various UI elements work now _so_ much better when you are able to swipe right (to easily navigate albums in a scrollable carousel) or swiftly swipe downwards (where on desktop one must find and drag a scrollbar).
I imagine we've all experienced some of the more irksome manifestations that have already transpired due to this schism such as: websites that tell you to download an application, a support call for a broken web function that results in "use the mobile app, it works there" and isn't fixed for weeks or months, or the horrific pop-ups that encourage the use of one or the other application as dev teams hint at their disinclination to continue minority support.
