Which dictionary is the best?

"It can be a challenge to get at what sets a dictionary apart from its peers. First, you have to move beyond the marked family resemblance (thumb index tabs, speckled pages, and a preference for the name Webster), the swaggering jacket copy ('The most useful dictionary you can own,' 'The most up-to-date dictionary available,' 'America's favorite dictionary,' etc.), and the shrink-wrap put in place to encourage you and your grubby hands to judge a book by its cover alone..."

I haven't used a dictionary outside the computer in years. But then again, the feeling of perusing one is an experience in itself. Specially if you don't know how the word is spelled.
