Introducing the new Mac mini. Just connect this tiny 6.5-inch-square Mac to your own display, keyboard, and mouse and you've got an instant desktop computer loaded with Mac OS X Snow Leopard and iPhoto, iMovie, and GarageBand. The new Mac mini features a faster processor-up to 2.53GHz-and up to 4GB of memory. That's twice as much memory as before. It also comes with up to 320GB of storage space and high-performance NVIDIA graphics. What doesn't Mac mini do? It doesn't waste energy. Mac mini uses less than 14 watts of power when idle, making it the world's most energy-efficient desktop computer. Starting at $599.

The new iMac features a brilliant 21.5-inch or 27-inch LED-backlit display with a widescreen 16:9 aspect ratio-perfect for watching HD video. The 21.5-inch display offers 1920-by-1080 HD resolution, and the 27-inch display goes beyond HD with 2560-by-1440 resolution. Dual-core Intel processors now start at 3.06GHz, available quad-core Intel processors boost performance up to 2x, and advanced graphics make the most of every pixel. iMac declutters your desktop with the Apple Wireless Keyboard and the new wireless Magic Mouse: the world's first Multi-Touch mouse. The 27-inch iMac starts at $1699. The 21.5-inch iMac starts at $1199.

Introducing the all-new Mac Pro. It's nearly twice as powerful, thanks to the next-generation Quad-Core Intel Xeon "Nehalem" processors and new system architecture. Each processor features an integrated memory controller, three channels of 1066MHz DDR3 ECC memory, 8MB of fully shared L3 cache, and Turbo Boost and Hyper-Threading technologies. The result? The fastest Mac ever. The NVIDIA GeForce GT 120 graphics processor with 512MB of GDDR3 memory provides up to 2.9x the performance of previous Mac Pro standard graphics cards. For even more graphics power, the optional ATI Radeon HD 4870 with 512MB of GDDR5 memory is up to 2x faster than the GeForce GT 120.3 With the new Mini DisplayPort and dual-link DVI port, you can connect a 24-inch Apple LED Cinema Display and a 30-inch Apple Cinema HD Display. The entirely redesigned Mac Pro interior makes it even easier to add and remove memory, expansion cards, and hard drives. The Mac Pro also features massive storage and expansion options: up to eight DIMM slots for up to 32GB of memory, four cable-free direct-attach hard drive bays for up to 4TB of storage,2 and four PCI Express 2.0 expansion slots. An all-new optional Mac Pro RAID Card brings data protection and increased hard drive performance. Front and rear FireWire 800 and USB 2.0 ports make it easier to connect external devices. It's the most advanced Mac Pro ever.
