My sister loves her Kindle and reads on it more often than she reads actual books. I'm the exact opposite. While I do read books on my Kindle Fire, I tend to use it more to check email, surf the internet, check Facebook, and play a couple of games.
I find that I prefer the paper version of a book versus reading on my Kindle. I think my main reason for this is because I love to read in bed and I'm afraid I'll fall asleep with the Kindle. I can't tell you how many times I've fallen asleep reading only to have the book fall to the floor sometime during the night. I worry that I'll do the same thing with the Kindle and it'll end up breaking.
Just because I'm curious, I thought I'd conduct a poll - Which do you prefer? Physical books or an E-Reader? Why?
