The day may soon be approaching when consumers will be able to walk into a Blockbuster store and rent a movie by downloading it instantly onto their video iPod or similar device. "We think the ultimate solution is a kiosk in a Blockbuster store and outside of a Blockbuster store that ... will be able to distribute content to your portable device," Blockbuster Chairman James Keyes told a Citigroup investors conference in Phoenix Wednesday. He predicted that video discs will become a thing of the past and that most movies will be rented in digital form. Keyes also said that he expects Blockbuster will benefit from an extended writers' strike as people alter their viewing habits and turn to movie and TV rentals as an alternative to the networks' planned menu of reruns, reality shows, and news magazines.
