But I don’t want to buy a Kindle
You don’t have to. It’s Christmas and someone might gift you one. I am kidding, because with the range of free reading apps from Kindle, you don’t really have to make anyone plonk down $100 or more. The free Kindle reading apps cover the gamut – from smartphones and computers to tablets.
You don't need a Kindle to read Kindle ebooks.
I own a couple of the devices, but I spend hours each day reading with the Kindle app on my iPad. Whenever I go out, I fire up the Kindle app on my phone so I can read in the supermarket queue and at the coffee shop.
It's amazing: wherever and however you read, you'll always be in the book and at the "page" you were last reading.
If you love books, you're in heaven. You can read wherever you like. :-)
