Do you design/develop a site primarily for the laptop/desktop and think about mobile later, or do you design your website to be mobile and unmobile friendly, therefore cutting design/dev time in half?
I'm not talking about using conditional elements to detect if someone is using a certain type of phone or a specific screen. I'm talking about being smart about site design/development and making it so you don't have to make two copies of one image, or two different CSS style sheets for mobile and non-mobile. I'm talking about thinking about your code and making it friendly to both ways of surfing the internet without any crazy coding tricks or hacks.
