Nice straw man and shoving words into another's mouth.

When the product suits one's purpose, it's viable. When it doesn't, it's half baked. When the original iPhone was released, the bar for viable was much lower. Other smartphones were a mess, UX-wise. Just fixing the UX with a smaller feature set won over a mainstream audience.

Now, the bar for viable is much higher, and it carries the expectations of a Maps application that works at least as well as Google Maps for iOS.

Customer expectations change over time. Pretending that they don't for the sake of argument is either foolish or dishonest.
