I guess it depends on the technical usage. I still go back to my college era calculus and physics books. Expensive at the time but worth it's weight in gold. For emerging technologies (hot, new languages) I prefer StackOverflow, Google, and wikis. I'd only give ePubs a shot if the price was substantially cheaper than the dead tree version. I'd still buy an iPad, but only for light reading and the 100k apps.
