Not all components are created equal. In most apps there are a set of components that repeat often. For us, these components are rows (or table-cells). Looking back, I wish we had taken more time to think about the rows and come up with a stronger set of patterns and components. In the end, we wound up with many different kinds with some inconsistencies.
We created one set of these components for phones (iOS and Android), and adapted them to tablet sizes from there. Tablet components are largely the same as those for mobile, and on a technical level the code only needs to exist once in two different styles. With this system components can vary in their look and positioning, similarly to the way responsive design works for web. Designers can then design a screen once using common components, and it can be easily adapted to different screen sizes as well as to iOS and Android.
Shortly after moving to San Francisco in October 2007, roommates and former schoolmates Brian Chesky and Joe Gebbia could not afford the rent for their loft apartment. Chesky and Gebbia came up with the idea of putting an air mattress in their living room and turning it into a bed and breakfast. The goal at first was just "to make a few bucks". In February 2008, Nathan Blecharczyk, Chesky's former roommate, joined as the Chief Technology Officer and the third co-founder of the new venture, which they named AirBed & Breakfast. They put together a website which offered short-term living quarters, breakfast, and a unique business networking opportunity for those who were unable to book a hotel in the saturated market. The site Airbedandbreakfast.com officially launched on August 11, 2008. The founders had their first customers in town in the summer of 2008, during the Industrial Design Conference held by Industrial Designers Society of America, where travelers had a hard time finding lodging in the city.
