Once, a couple of years ago, I thought one would be enough, a couple of months ago it was six (although that was between two people), but then having seen the latest Amazon new Kindle Paperwhite it's now definitely seven.
However, this is not so much a blog about why you should get the new Kindle Paperwhite, but rather why my wife and I ended up with six eReaders between us.
Firstly, a little bit of history. The first Nook came out on 30 November 2009 and my wife was immediately interested in it. Firstly as a way of prolonging the day before we'd have to get a bigger house to store all the books we have, and secondly to make it easier to read the enormous fantasy tomes she was starting to get into. One problem, however, they weren't available in Australia.
On the other hand we were going to America so I got dragged into a couple of Barnes and Noble stores while she talked to the sales person about the Nook. I have to admit it wasn't that much of a trial, a whole room of history books - I was in heaven.
