I understand Kindle to be a brand name of a tablet computer. Does this mean that if I buy the "Kindle Edition" of a book I won't be able to read it on my PC or Samsung tablet? Sometimes a book in Kindle Edition is cheaper than elsewhere, but I want to know that I'll be able to read it without having a Kindle device. Is this possible?
Kindle is the brand name of a range of e-readers and tablets (called Kindle Fire) produced by Amazon. Typically books bought as a Kindle Edition will be downloaded directed to a Kindle device attached to your Amazon account.
If you want to read Kindle Edition books on a Samsung tablet or desktop PC then you'll need to download the Kindle app for your device. There is an Android version and a PC version, as well as several other options.
You can click the "Read with Our Free App" or "Read on Any Device" (or similar text) link below the price for an overview and links to more detailed information.
