Steve Jobs is preparing another "turtleneck and jeans" address tomorrow to unveil Apple's new crop of toys. Last week brought the relatively quiet upgrade to the iMac line. The speculation on the Internet is that Apple will announce new iPods, movie downloads (as suggested by the "It's Showtime" tagline for the event), and perhaps some sort of integration with home theaters. Jobs does like to trot out surprises, so we'll see if there's "just one more thing" to wow the faithful. The presentation starts at 1pm EDT.
