Craig Pickering of 37signals talks about the (in my mind unfairly) maligned UI for TripLog/1040, a native iPhone app for logging reimbursable miles during business trips. I hadn't heard anyone refer to UI elements as "stacked in time" or "adjacent in space" before. Excellent ways to sum up these concepts. It's also worth reading the developer's rebuttal to the vitriol being spewed over at Flickr.
Whaddya think?
