Here are my slides that I used for the responsive design session in SharePoint 2013 at SharePoint Saturday. Hope you had as much fun as I did.
Key takeaways are:
- don’t wait to make your sites available for mobile devices, the time is now
- device channels is the sharepoint solution when you want to deliver different content and pages to different devices
- media queries is the solution to deliver the same content to all devices
If you ask me what the best option is, I would go for the media queries.
