Haha, I use Chrome's emulator which covers most use cases. I use SCSS with CodeKit but only so I can do @import's of for example my global.css into specific page CSS files. Not any crazy stuff. I'd love to use variables though as that'd save time, although a find and replace over 20 files in Sublime Text also works fine!
It's really important my site works well on mobile. So I've spent a lot of time adding countless media queries. Simply keep adding more until it works on every device (in the emulator).
