big-daddy

柿生くん，以下のbig-daddyとは？（院生 Yoko）
(CNN) -- Something weird is happening to mobile phones: After shrinking from enormous Zack Morris proportions in the '80s and '90s, they're getting bigger again.
So big, in fact, that some won't fit in jeans pockets anymore.
The Dell Streak, which is set to be released in the U.S. later this summer, is the biggest of the big-daddy phones so far, with a 5-inch screen. The screen of the iPhone 4, by comparison, measures only 3.5 inches diagonally.
