Apple CEO Steve Jobs introduced a 17-inch widescreen LCD iMac at Macworld Expo, New York today. The company also reduced the price of the top-end 15-inch LCD iMac by £100.

The new high-end iMac's 17-inch screen features an 800MHz G4 processor, an Nvidia GeForce4 MX graphics card, a SuperDrive and an 80GB hard drive, capable of holding over six hours of video, 15,000 songs and 73,000 digital images.

Like its 15-inch model, the 17-inch iMac lets users adjust height and viewing angle with “just a touch”. The screen is one-inch thick and has an aspect ratio of 16:10, so users can watch DVDs in letter-box format. The LCD screen offers the same viewing area as a 19-inch CRT monitor, delivering a resolution of 1,440-x-900 pixels, which Apple calls 64 per cent more pixels than the 15-inch iMac.

“The best consumer desktop just got even better,” said Steve Jobs, Apple’s CEO, during his opening Macworld Expo keynote speech this morning in New York. “Having this gorgeous 17-inch flat screen floating in mid-air right in front of you is simply breathtaking. There’s nothing like it in the PC world.”

“Our customers wanted a larger display,” Jobs told his audience at the end of the keynote. “This iMac display is both giant and beautiful!”

The Mac ships with iTunes 3, iPhoto, iMovie and iDVD.

Other features include: two FireWire and five USB ports; built-in 10/100BASE-T Ethernet; a 56K V.90 modem; an internal 18W digital amplifier and Apple Pro Speakers; Mac OS X 10.2 and a selection of productivity and entertainment titles.

The Mac ships next month and will cost £1,649 (inc. VAT). The top-end 15-inch LCD iMac now costs £1,499 - down from £1,599.
