When Amazon launched Amazon Prime in 2005, it didn’t offer that much in the way of benefits — just free shipping on Amazon goods. Now if you pony up $79 per year, you get some good cultural perks: You can borrow over 145,000 e-books and read them on your Kindle and devices with Kindle apps. What’s more, you can stream thousands of movies and TV shows through your computer, select blu-ray players and now … drum roll please …. the iPad. Just yesterday, Amazon released its free iPad app, which means that Prime members can start streaming movies on their tablets right away. If you’re not a member, you can always try out a one month Free Trial to Amazon Prime. And if that doesn’t move you, you can simply dive into our collection of 500 Free Movies Online. Ars Technica has more details on the pros and cons of the app here.
