When reading the design guide here: http://www.magentocommerce.com/design_guide/articles/working-with-magento-themes
This folder structure is often mentioned:
‘app/design/frontend/my_interface/my_theme/’ AND ‘skin/design/frontend/my_interface/my_theme/’
My question is what is my_interface, is that pc, tablet and mobile and so fourth? What different interfaces can magento detect?
my_interface is just a name of your design package. Themes are groupped inside design packages. Inside that pcakage, my_theme is the name of the theme. You can have many themes inside a package. Default theme is always named default and other themes inherit from that default theme - so you can easily create any numer of sub-themes that override selected parts of the default theme.
