Kindle for PC
Kindle for Android with Whispersync

That famous e-book reader without having to spend one cent on the hardware. Well assuming you already own a smartphone or computer.

For PC version is not as easy to read but is very fast.

For Android version much easier to read, also has a better format.

The PC version tries to imitate a Mac experience which I never liked. The list in Android makes every seem organized. On Android there is a Whispersync feature that syncs all versions of your Kindle this way you never have to scroll through the pages.

Here's why this is a 70% program...
Pros

1. Android version is better
2. Books make you smarter 
3. Thanks for the Sepia option

Cons

1. PC version make my eyes twitch
2. Still they are books
