Oh dear. I'm afraid I'm not going to the take the requisite dozens of hours to be sure by learning this keyboard and making a truly "fair" comparison, but I'd bet I'm faster swiping with the current keyboard than I would be on this one. Swiping is why I can use words like "comparison" or "requisite" on a phone without giving it much thought anymore. I'm still faster on a real keyboard, especially as I rarely get those "tried to write 'hello', got 'grump'" sorts of errors with a keyboard, but it's a lot closer than it was when mobile devices first came out out and Palm's Graffiti input was considered a major breakthrough. (Laughable by modern standards.)
