How much have you saved by buying an ereader?
I am curious has anyone computed how much they have saved by buying an ereader then: followed this formula
take the cost of the ereader/number of months you have had it-amount you have saved on the ebooks = TCO (Total Cost of Ownership) or how much does it cost you to own this device. If your number is negitive it means that you have saved more than the value of the reader itself and I believe that would be called your ROI (Return on Investment). I am far into the negitive numbers.
