In the 25 months since I bought my Kindle, I've spent an average of about £16 ($25) per month on ebooks. That doesn't seem as bad as I feared.
I have one magazine subscription (which I should probably cancel - I'm not sure I've even taken the issues out of the envelopes for about two years) and I buy a newspaper every Saturday (mainly for the TV guide). I also haven't managed to give up paper books. Or probably even cut down very much. I expect it adds up to about the same again.
Although I feel I should point out that they were all
bargains.
