The Mac Expo tradeshow today kicked off in London with announcements of new products from Quark, including QuarkXpress Interactive Designer, the company's new Flash tool as well as QuarkXpress 7.02, an update to the only Universal professional desktop publishing solution. Other announcements included Miglia's TVDuo, which the company claims is the world's first dual digital TV tuner for Mac systems. While Apple did not have any announcements, we have posted a photo gallery of Apple's booth from the London show.
