But there are also benefits to ereaders. I live an hour away from London on the train, and I go there for a night out probably just over once a week on average, as well as fairly often going there and other places for meetings. Until I got a Kindle I would chose between taking my bag with iPad and/or a book, or having nothing to do on the train - the latter on occasions when having a bag with me would be a nuisance the rest of the time. Now I can always read on the train, and it slips into my pocket the rest of the time.
Equally for longer journeys, whether it's a couple of days back where I come from (Oxford, ~3.5 hours away from me) or a longer trip, maybe abroad - as I'd always have a bag and/or suitcase taking a book wasn't a problem, but now I don't have to think about how many books I need, or how much space they'll take, and if I fancy a break from what I'm reading I have 100s of alternatives ready to go.
But yes, there's plenty of times I'll chose to pick up a physical copy rather than the Kindle, and plenty of books I have in both forms.
My cargo pants pockets exactly fit a paperback book, and if I ruin a paperback by being caught in the rain I'm out at most $8. Books are a great combination of disposable and persistant. I can read a book one-handed, in the bath, and can easily and quickly share books with friends or use them to answer questions I am asked.
More than half of my library has been bought used, most for $2-$4, which no eBook even comes close to on price. The best thing about eBooks is how much cheaper the paper versions have been as everyone else sells them off.
eBooks have a long way to go before they are as useful to me as a physical book.
