Apple CEO Steve Jobs has moved his Macworld San Francisco Expo keynote speech forward a day to Monday January 7, 2002.

Originally scheduled to give his address on Tuesday January 8, Jobs is now addressing the host of Mac fans at Macworld Expo San Francisco, a day early. Macworld Expo San Francisco Conference & Expo runs from January 7 to 11 at the Moscone Center, San Francisco. However, the show-floor expo part of the event is still due to begin on the Tuesday, with the conference programme starting on the Monday.

Jobs said: "We’re working hard to make this January’s Macworld the most exciting ever."

He added that there was a record attendance at Macworld Expo New York in July of this year: "We’re hoping to break the record this January too."

Charlie Greco, president and CEO of IDG World Expo - organizers behind Macworld Expo - said: "Steve’s keynote is a great way to start what will be a very exciting and informative week for all Macworld attendees.

"We’re thrilled to move the keynote up to Monday, and begin the excitement a day sooner."

Asked why the keynote date had been moved, Beth Williamson, IDG World Expo PR, told Macworld UK: "Apple asked us to move it." She didn't know the reasons why.

Steve vs Bill? Interestingly, Microsoft's chairman and chief software architect Bill Gates is giving a keynote at another show, CES (Consumer Electronics Show), on 6.30pm Monday evening in Las Vegas - which would have preceded the Jobs Macworld Expo announcements.

Now, Steve is ahead of Bill again.

In October, Apple announced its iPod digital-music player one day before Microsoft introuced its Windows XP operating system.

Show-goer frustration The keynote switch is bound to frustrate those show-goers who have already booked travel and accommodation to ensure that they see the Steve Jobs keynote. Any keynote attendees will also have to wait a day for the Expo proper to open.

Show organizer, IDG World Expo, has pulled together contingency plans for prospective Expo attendees now forced to change their travel plans.

Williamson explained: "Those in that situation should contact ETMI (the preferred travel advisors for the event). They are all set to go, and have rooms and air tickets available at the lowest prices we could secure," she explained. ETMI can be contacted on 001 781 329 1888 from the UK.

Rob Halpin of IDG Expo's independent PR consultants, MS&L, explained: "We (the organizers) don't know why this has taken place. There's already a lot of buzz floating around this show."

Apple is widely rumoured to be unveiling a flat-panel iMac at the show. Apple refuses to comment on future products.

Tickets for the events are available by registering on line.
