Shopping for plane tickets will never rank among life's greatest pleasures. But with Hipmunk, it's no longer among the most tedious. This slick site lets you search for flights across major airlines, giving you easy-to-scan results in a grid sorted by agony ("a combination of price, duration and number of stops"). Nice touches include an icon that highlights flights with wi-fi, and there are iPhone and iPad apps that let you use the service on the go. Did we mention that Hipmunk's mascot which looks like the chubby-cheeked offspring of Rocky the Flying Squirrel is cool?
