You can find a lot of apps for free on Google Play. I showcase free apps all the time at my Apps page. But it's not every day you can get some of the top paid apps without actually paying.
Today is that day thanks to Amazon. The online retailer is giving away $100 worth of popular, paid Android apps for free. That includes games like Plex and Sonic the Hedgehog 2, as well as handy apps like AccuWeather Platinum and Root Explorer.
