From Apple’s press release

Apple today announced updates to its iMac and Mac mini desktop lines, including a 24-inch iMac that is priced more affordably than ever before and a Mac mini with powerful new integrated graphics. For the same $1,499 price as the previous generation 20-inch iMac, the new 24-inch iMac delivers a 30 percent larger display, twice the memory and twice the storage. Delivering up to five times better graphics performance, the updated Mac mini now features the same groundbreaking NVIDIA GeForce 9400M integrated graphics introduced with the aluminum unibody MacBook family. The Mac mini is the world’s most energy efficient desktop, drawing less than 13 watts of power when idle. All iMac and Mac mini systems come with Mac OS X Leopard, the world’s most advanced operating system, and iLife ’09, Apple’s unparalleled suite of consumer applications for managing and organizing photos, making movies and creating and learning to play music.
