I'm not a fan of ebooks generally, but would love to have a tablet that could replace a bunch of technical books and papers. Any of the e-ink readers refresh too slowly to really allow skimming, but maybe the iPad or Android tablets would be better. Something like a split pane view for PDFs where you could 'dock' a bunch along an edge for quick reference, or even have multiple papers open at once. I don't know that current devices are either quick enough to render pages quickly, or have enough memory to cache the current page +- 10 others.
