mobileOK is largely orthogonal to questions of "one web" and content adaptation, and by design. As Jo says, mobileOK says nothing about desktop content and doesn't care how you decided to cough up your mobile content. However, the mobileOK test does contain a subtle assumption that it is being applied to a mobile-specific URL -- e.g. m.gmail.com and not gmail.com -- and this is why it says you should default to delivering mobile content. This in turn has some implication for how you do content negotiation / adaptation between desktop and mobile content. >From my time galloping across the mobile web, I believe the large majority of sites do use a different set of URLs for mobile content (and possibly the desktop property redirects to the mobile property), and, it's these sorts of sites and URLs that mobileOK is targeting. This model, by design, fits neatly with mobileOK. It's also entirely legitimate to serve desktop and mobile content from the same URLs. I can understand that the right default for such sites is often desktop content, which seems to be a problem in theory vis-a-vis mobileOK. In practice, there is no mobileOK test that tries to determine what your default behavior is. The tests always use an Accept header that asks for mobile content, and a fixed User-Agent. Regardless of content negotiation / adaptation strategy, it should be possible to determine that the test requests want mobile content. So, the note about defaulting to mobile content may not present a problem in practice. As a result, I'd also support removing this sentence, as it seems controversial and does not map to a real test anyway.
