When I was little I read paper backs by the thousands per day (ok... maybe not quite that much...) but after I got married we had to move so much (average of once per year) that I gave up my collection of books to libraries, Goodwill, and etc. Since then, other then blogs and the like, really fell out of the practice of reading... till I got my e-readers. Now I read again and loving it as much as before but with out limitations of paper books. Should loose my Nook Color (and my phone, and my tablet, and all e-readers) I would stop reading because... I no longer buy/store pbooks so I would be forced to stop due to lack of inventory!
However that would not last, I would replace one of the e-readers fairly quickly.
