Adapting the display of elements on the mobile skin helps to amend issues with the article content. So doing things like transitioning templates from a tabular layout to  tags, designing with the mobile preview in mind, using things like horizontal list CSS and tweaking layouts to stack appropriately in Mercury.

I do want some basic customization, more in the way of theming. Other than strange template output in articles, I'm rather happy with the mobile skin and I prefer it over mobile Oasis.
