Designers certain can abandon breakpoints if they can find a way to do good design under purely fluid conditions—design that pleases the user, satisfies the client, and moves the industry forward aesthetically. But designers who persist in responsive or even adaptive design based on iPhone, iPad, and leading Android breakpoints will help accelerate the settling out of the market and its resolution toward a semi-standard set of viewports. This I believe. When I see fragmentation, I remind myself that it is unsustainable by its very nature, and that standards always emerge, whether through community action, market struggle, or some combination of the two. This is a frustrating time to be a web designer, but it’s also the most exciting time in ten years. We are on the edge of something very new. Some of us will get there via all new thinking, and others through a combination of new and classic approaches.
