We all know the fable of the tortoise ultimately winning his painstakingly measured race against the hare. Apply that to today's economy and it's relatively easy to come up with a winner for MarketWatch's third survey of the best U.S. cities for business. This year's victor is the subdued terrapin of regional economies: Des Moines, Iowa -- population 556,230. Des Moines handily beat all comers, including two-time winner Minneapolis-St. Paul, in a survey that was expanded on several fronts for 2009. Notably, the search for the nation's best business city included any metro area with a population of more than 500,000, thus expanding the eligible list to 101 from last year's total of 50. But we also threw in a few wrinkles to see how well local economies held up during one of the toughest years since the Great Depression.
