The Next Big: Summer Essential

The Margaritaville Frozen Concoction Maker is one of those rare appliances that signals a great step forward for modern man. Toss in some ice and liquid ingredients, flip a switch, and this electric wonder churns out pitchers of perfect summer drinks. One secret: It shaves the ice, instead of crushing or chopping it. Best of all, the maker can be used for smoothies as well (which might be a good idea the next morning). It's not cheap—$299.95 at Williams Sonoma—but can you really put a price on happiness?
