Apple seems set to deliver significant innovation this year, judging by a new message that's showing up on the front page of its US website.

"The first 30 years were just the beginning. Welcome to 2007," the message reads.

Apple's declaration of intent appears just one week before the highlight of the Mac calendar that is Macworld Expo, which begins on 9 January (with conference sessions starting on 8 January).

Macworld Expo is expected to be highly significant this year, with rumours of a new iPod model, a potential iPod mobile phone, new lightweight portables, monitors equipped with built-in iSight cameras, and the much-vaunted media streaming device iTV.

It's also likely that Apple will demonstrate more features in its powerful Mac OS X 10.5 'Leopard' (due to ship by spring); and the company seems set to reveal whatever new enhancements it has made to the popular iLife suite of creative consumer applications.

In the UK, Apple customarily uses the education trade show, BETT, to demonstrate some of its latest announcements from Macworld Expo. BETT begins on 10 January.
