DJ cum live music producer, Paul van Dyk weaves his own music on stage in real-time on a pair of 17-inch MacBook Pro computers running Logic Studio and Ableton Live. “Ever since I basically began making music, I’ve worked with Macs,” he says. “They’re in the studio as well as on the road. I’ve always had my Macs with me. They’re an essential part of my music.”

Apple today introduced the world’s thinnest notebook: MacBook Air. It measures an unprecedented 0.16 inches at its thinnest point while its maximum height of 0.76 inches is less than the thinnest point on competing notebooks. In addition to a stunning 13.3-inch LED-backlit widescreen display, MacBook Air offers a full-size and backlit keyboard, a built-in iSight video camera for video conferencing, and a spacious trackpad with multi-touch gesture support, letting users pinch, rotate and swipe. The new notebook is powered by a 1.6 GHz or 1.8 GHz Intel Core 2 Duo processor with 4MB L2 cache, and it includes as standard features 2GB of memory, an 80GB 1.8-inch hard drive, and the latest 802.11n Wi-Fi technology and Bluetooth 2.1. Starting at just $1,799, MacBook Air begins shipping in two weeks.

A backup appliance that works seamlessly with Time Machine to automatically and wirelessly back up everything on one or more Macs running Mac OS X Leopard, Time Capsule combines an 802.11n base station with a server grade hard disk in one small package. “Bring Time Capsule home, plug it in, click a few buttons on your Macs and voilà—all the Macs in your house are being backed up automatically, every hour of every day,” said Steve Jobs, Apple’s CEO. When it ships in February, Time Capsule will be available in models featuring 500GB and 1TB hard drives for $299 and $499, respectively.
