Both "unfeasible" and "infeasible" are words according to spell-check, and they appear have similar dictionary definitions. But what is the difference between the two words? Is one more acceptable to use than the other?

Jacking the Link From The Comment (Thanks Josh61), It seems that the words are interchangeable, and it matters not which you choose to use, and is completely down to preference.

One interesting thing to note is that the variant with the "un" prefix was the most common, until the 1970's when the "in" prefix shot past it by a long way. It would be interesting to know the reason for this, but I guess that is a question for another time.
