OS Vista. This is probably how Steve Jobs is hoping to attract attention on his Macintosh alternative, Leopard OS.The WWDS is usually held in late spring, but this year’s Mac-related event is special due to the big announcements that are expected during the one-week show.Definitely, a key presentation at WWDC is about the up-grade Apple plans for its OS, which is dubbed Leopard. It will probably be announced by Steve Jobs himself.But the surprise comes when we find out that PR managers at Apple are thinking to get attention by naming Leopard…Windows Vista 2.0! An occasional photographer actually captured this breaking news from Moscone Center, where WWDC is organized.The photos posted on Flikr.com also reveal how Apple is welcoming its visitors: “You've come to the right platform”. Apparently this platform is also making a daring step into the 64-bit processing, which is much closer now after the Intel-Apple alliance from last year.
