Gosh that's a good question ! If I added up my ereader's \ tablets over the years from 2010 on, it's about $1500. I bought all new and were on sale. Except one refurbished. So probably spent 2x more for ereaders than books. I also wait for sales on books, plus many are less than $5 or free. Maybe once a year I'll cave and buy a book at the publishers asking price of $12.99 or more. So given that it's over six years altogether, 2010-2016, I guess it's not as bad as I thought it would be.
