Support for mobile-enabled landing pages

We really need Marketo to provide better functionality with regards to mobile-enabled landing pages. A series of mobile-sized landing page wireframe templates would be a good starting point.

So many of our prospective customers are accessing our sites via smart phones, and with Facebook's forthcoming mobile ad platform soon to go mainstream, 'mobile-sized landing pages' seems to be a big missing piece in the Marketo jigsaw.

What are Marketo's plans in this area?
