No upgrade nightmares. Before you can even think about Vista, you’ll likely need a new PC. Or upgrades for memory, hard disk, and graphics card. Why go through all that hassle, when you can just get a Mac?

It’s simpler. No need to choose from the many (and expensive) flavors of Vista. Every Mac runs the same Mac OS X — with the full set of industry-leading features.

You don’t have to buy new stuff. Your existing printer, camera, keyboard, and mouse will work with a Mac. PCs and Macs can usually share peripherals if they connect via USB, FireWire, or Bluetooth, three industry standards available on every Mac.

Know iTunes? You know Mac. You’ll recognize features like the library collection, playlist arrangement, and instant search in many Mac applications. So you’re something of a Mac expert already.

Macs run Microsoft Office. Microsoft Office for Mac OS X gives you Word, PowerPoint, and Excel, all with familiar features and shortcut commands. For collaborative work, Office for Mac connects to Microsoft Exchange servers.

You can take it with you. Most popular applications for Mac and PC use the same file formats, making it simple to exchange documents with friends and coworkers or move existing files from a PC to a Mac.

The new MacBook has something for everyone. Less than an inch thin and 4.5 pounds, it fits your backpack. It offers great integrated graphics performance for playing 3D games or creating photo books in iPhoto and making movies in iMovie. And it has all the MacBook features you want at a price you’ll adore.

It’s all about performance. If you want desktop-class graphics and a bigger display, you want the all-new MacBook Pro. With a double graphics punch, the 15- and 17-inch MacBook Pro models are fast enough to run the most graphics-intensive games and professional applications, but portable enough to come along for the ride.

MacBook Air travels light. At just 3 pounds, it sets a new standard for mobile computing — without scrimping on features. With more power, advanced NVIDIA integrated graphics, a 13.3-inch screen, a full-size keyboard, and breakthrough wireless innovations, MacBook Air is engineered to take on the wireless world.

iMac packs a complete, high-performance computer into a sculpted, thin design. Available in 20- and 24-inch widescreen models, iMac includes advanced NVIDIA graphics and up to 4GB of memory standard. With the new iLife ’09 and Mac OS X Leopard, you can organize photos, make movies, learn to play music, and more.

The Mac Pro is a force to be reckoned with. With the Quad-Core Intel Xeon “Nehalem” processor and powerful AMD and NVIDIA graphics, it’s nearly two times faster than the previous generation. Designed for easier expansion, every system supports up to two 30-inch Apple Cinema HD Displays, along with millions of configuration possibilities.

Mac mini packs a complete Mac experience into a 6.5-inch-square frame. Even with a more powerful Intel Core 2 Duo processor, Mac mini uses less energy than ever before. Just connect your own display, keyboard, and mouse — Mac mini brings the rest.
