Some time ago I fight against a mobile site because of the full graphical design that the customer approved. No one of the designers was aware of the mobile complexity: different screen sizes, high DPI screens, rotation and so one. Last but not least the .mobi problem with Apple devices.
The so called waterfall of resources loaded by a mobile device is most of the time the same of a desktop browser… but the two have different connection capacity and memory and CPU power.
Can the design address some of these performance issues? How? And what about the Responsive Designer?
Take the time to look at this presentation: more than useful!
