So meet the family. These are premium products at non-premium prices. People are going to love these products.
This is Amazon's mission statement for product development. They will not compete with Apple's "revolutionary, magical" phones and tablets; instead, they'll sell quality tablets and readers to the average person at great prices. This populist attitude has been missing from the tablet market since the iPad's release.
The Fire will be the first successful Android tablet because the user base already exists. With the last few Kindle generations, Amazon has groomed customers to pay for electronic content. These users will buy Kindle Fires and e-Ink Kindles in droves, buy more books, and tell their friends.
At this price, Amazon won't steal Apple's customers. They will simply introduce a new segment of people to the tablet market. Developers need to think about this as another golden ticket. Here's the iOS gold rush, part deux.
EDIT: changed "luxurious" to "revolutionary" after reading a comment below. I need more coffee.
