Khoi Vinh is Jeffrey Zeldman's guest this week. Khoi is a Principle Designer at Adobe, design chair at Wildcard, and former design director at NYTimes.com. He blogs at subtraction.com. The two designers discuss the surprising results of Khoi's recent design tools survey; being creative on the iPad; the inspiration behind Adobe Comp CC; juggling multiple projects to stay fresh; choosing an extracurricular project; how design has changed in the past two years; how to watch TV; and more.
