I agree that a multidevice, always-available solution is better for many activities, especially for news, but the downside to this requirement is that desktop apps become unimaginative, blown-up versions of the mobile apps.

I want more developers to create unapologetically desktop apps — unconstrained, customizable, with multiple and filterable views of content, able to integrate and share data with other apps.

(Yes, these are not mutually-cancelling goals. You can have a good enough iOS app and a more interesting Mac app. However, developer time is finite, features beget bugs, and only a small fraction of users collaborate with an open source project)
