Whereas my brain boggles at how big a pain it must have been to do a literature review pre-JSTOR/Web of Science/pdfs in general.

I am a voracious reader (generally 2-5 novels/equivalent per week, depending) and love ebooks. Carry 5 long novels, 3 YA series, 4 non-fiction books, my work literature, and an assortment of my favorite comfort/pickmeup novels/short stories/essays with me constantly and instantly searchable? Yes please.
