I think the the author is greatly overstating how big the tablet market is for the product strategy he's hoping for. "Tablet-optimized apps" are a historical artifact of the 2010-2015 period when tablets were a new and exciting category of internet-connected gadget with a plethora of use cases in entertainment and productivity, held back only by 'blown up' versions of mobile apps. Within a few years however, most apps people use (Netflix, Office, Google Docs) were redesigned to scale to the size of the screen, in the same way websites do.

A decade on, the market has spoken. Tablets are overwhelmingly used for Netflix, YouTube and casual mobile games, use cases where specs don't matter and every tablet is more or less "good enough". Maybe a million or so users have an iPad for digital art or as a laptop replacement. Even the cheapest model iPad has pen, mouse and keyboard support. So what would an iPad Neo add?
