Device Channels are a way to apply a certain look to a certain device. A device can belong to multiple channels. Publishing sites in SharePoint 2013 are optimized for mobile development, and the Device Channels feature can be used to fine-tune how mobile users experience the site. Device Channels also leverage the Search Engine Optimization (SEO) capability.
Both of these features can be leveraged by users for designing either Intranet or Internet web sites. They ensure that Internet sites will also cater to the growing mobile audience using smartphones and tablets.
Our Take: There is some controversy among SharePoint pundits around the new Design Manager feature, and how mature and easy it is to use. The new branding model is not proven, and early reviews still call branding activities cumbersome. However, there are some solid benefits that will become more evident as use of Design Manager matures.
Designers can still use master pages if they choose to, so Microsoft has not deprecated that functionality. We are seeing designers use a combination of old and new design features. The out-of-box rendering, particularly for mobile views, is still somewhat weak
and requires custom development.
