I shoot slides in part because I can project the images at a higher quality with a slide projector than I can with a digital projector (not to mention the difference in price between the two!) Having said that, the iPad and its ilk could finish slide film off. The new iPad announced today has a 2048x1536 pixel display, which is higher than that of an HDTV at slightly more than 3 MP. Get it up to 6 or 8 MP and I might bite for the right price. 'Til then, slides are the way to go for me.
