As a student of Zen Buddhism, I'm always a little bothered to see yet another thing called "Zen" that has virtually nothing to do with Zen, or Buddhism. The authors seem to think that "Zen" is a synonym for "calm," even though calm abiding is only one small aspect of Zen. If you read any of the classic Zen literature, like the Gateless Gate or the Blue Cliff Record, you'd come away with the impression that Zen is very active, vital, and vigorous.
But with a name like Zen, I at least expected the browser to be one of those tabless ones that encourage you to focus your attention on the present task, by enforcing one web page at a time. Or a text-based one, like w3m, that removes graphics to allow you to focus on the words. While the Zen browser interface is a little cleaner, with fewer buttons and things, that doesn't necessarily translate to "calmer." Calm is what you bring to the browsing experience, not what you take away from it.
