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.
