i read the same amount at home, but where the Kindle comes into its own for me is while travelling.
I spent 2 weeks in an all-inclusive resort a couple of months ago, just pure relaxation. I ended up reading 12 books over the 14 days. The convenience of having the books was the main reason for reading so many.
on the last 2 week holiday i brought 4 books because of bag weight restrictions. I ended up swapping books with other tourists, and reading books that i wouldnt normally read. IT was both a good and a bad thing as some of the books were truly rubbish.
