I see Ubiquity as one big UI experiment, which is nice. Windows NT and OS X aren't the last words on GUI. That said, I'd like to see some data guiding these decisions. Does Firefox report back to the mothership about tab usage? Their central argument for this UI, in the article at least, appears to be this: "Reichenstein argues that tabs were a good solution for an earlier age of the Internet, when users hardly ever had more than ten tabs open at any given time. Now, however, as browsers are slowly turning into operating systems, a new paradigm for organizing this information has become necessary." Is this true? Does this jive with data about how people actually use browsers and tabs? I have no idea, but I want my experiments to be backed by data, you know?
