I was given my Kindle as a present last Christmas. I love it...so easy to use. Handy for reading in bed..lighter than a book and you don't loose your page if you fall asleep while reading. Being able to change the font size must be a bonus to people with poor/failing sight and not having to cart around a pile of books in my luggage when I go on holiday is something I am looking forward to. Downloading a new book is so simple and extrememly fast. From deciding I want to read a certain book to starting reading it can take less than a minute.
When my Kindle started to play up a couple of months ago it was a simple and painless process getting a replacement...it came in the post the day after I contacted Amazon Customer Services...no quibbles, no fuss. Can't fault the customer service I received.
