I read an awful lot online. I still probably invest significantly more time with physical books than in frequenting websites, but the weekly averages spent on each activity are a lot closer these days than five years ago, and getting closer still. Books are better for long-term perspectives on the world around us. The internet has the advantage of being current, and of telling us what other people like us (and not like us) are thinking and doing.
My book collection (not my ebooks, sadly) has this advantage over digital text, online or in other forms: Amazon and/or other interested parties cannot make it disappear. Even when they try really, really hard.
