The Kindle

So 2 years ago Rob (my boyfriend) bought a Kindle. He swears by it. Well, recently he read a series I recommend to him which he downloaded onto the Kindle. When i finally got around to reading it I COULD NOT. I mean seriously, I am a book worm...the child who went to dentition for reading in class....and I COULD NOT READ IT. I tried a few different times and gave up. A few days later I saw one of my series came out with a 4th book, so I bought it....and finished it in a week! What the?! Tried the Kindle again...NOTHING. This week Rob went out of town and took the Kindle with him so I decided to buy the book I had been trying to read in paperback....and I am HALF WAY FINISHED ALREADY.....what the psyc?
