Trade-offs to accommodate your resource or skill contraints are just that -- trade-offs. They're not optimal solutions for your users or your products. Singular dedication to user experience may have an intangible value, but Apple and others have consistently demonstrated that the value is high.

This isn't a trade-off Facebook needed to make. Whether it's a trade-off your organization needs to make depends on your resource availability, skills, and target market. However, there's no value in dressing up the trade-off as anything other than a trade-off.

The target market and product factors into the question of resource allocation. Nest would not have made such a splash if they decided to skip user experience and focus on fast feature roll-out, and Dropbox would not have succeeded to nearly the same degree (if at all) without first-rate native user experience.
