> I'd say the second biggest reason is the annoying user interface DuckDuckGo is the first website that made me want to install a browser plugin to change the way the page looks. (As for other websites that had a look I didn't like, I simply stopped visiting them.) The problem with installing plugins, though, is that I use several browsers on several computers, and to get a consistent look, I'd have to customize all of them (if possible).

DuckDuckGo does have a very annoying default color scheme. Fortunately you can turn it off in the settings page: http://duckduckgo.com/settings.html.

I think google is actually easier (or as easy) to type compared to bing. Look at the position of your fingers as you type it.. the repetition of G/O and the close proximity of L/E respectively makes it a easy to type without looking at the keyboard.
