Craig Z. I'm new to Marketo and had the same question regarding mobile friendly landing pages. I just came across a video under Release Notes: January 2015 that starts out, "If you accepted the Beta invitation...." I haven't seent an invitation, but would also like this feature.
I was looking for it this morning as well, and thought I might have missed something... Maybe they're rolling it out? It sounds like Dan Stevens had luck with it earlier this weekend but I haven't seen it yet.
And here I thought I was going to be productive during this blizzard we're going to get :)
This is currently being rolled out and as per the release notes it may take a week to enable this on all customers instances.
"Mobile Friendly Landing Pages
You can now build mobile views for landing pages from within the landing page editor. Deliver your message effectively regardless of device and increase engagement by tailoring your content for easy consumption on-the-go. This feature will rollout gradually throughout the week following the release. "
