Exactly. What is the point of Jony Ive sweating over every tiny physical design detail if the software is rough-shod and negatively taints the entire user experience?
Scott Forstall was fired over the poor quality Maps app. However Maps is an intrinsically difficult challenge. The app itself is just the tip of the iceberg; underneath it is an immense undertaking requiring gigantic databases, fleets of camera cars, etc. Probably nobody could have produced a near competitor to Google Maps on the first release.
By contrast the Podcasts app is just an app. The failure to work full screen on an iPad is slipshod programming and testing. It looks and feels cheap, like a blunder in a high school programming exercise. The decision to knowingly ship it in that state speaks poorly for the personal integrity and professionalism of the product management, programming and testing teams. With many other companies a glaring issue like that in a common-path user area would be an unquestioned ship stopper. Does nobody have any pride in their workmanship?
I just finished talking with Apple Support -- their recommendation (which I have in writing) is to not use the Podcasts app but rather use Downcast from the App Store.
