The new models now include an "HD display with polarizing filter and anti-glare technology for rich color and deep contrast from any viewing angle." Plus the dual-antenna Wi-Fi is supposed to be much faster than traditional Wi-Fi.
Amazon is introducing these new tablets with a novel way of providing 4G data: "Get 250MB a month for 12 months with a one-time payment of $49.99." In comparison, a device like an iPad will run you about $230/year for 250MB/month of 4G data. If wireless providers continue to offer this type of data package for the Kindle Fire, that's going to be an important differentiator that will give the Fire a unique competitive advantage.
We also can't forget that Amazon provides a unique ecosystem through Amazon Prime:
- Prime Instant Video - unlimited, instant streaming of thousands of popular movies and TV shows
- Kindle Owners' Lending Library - Kindle owners can choose from more than 180,000 books to borrow for free with no due dates
Since the Kindle Fire runs a modified version of Android, it won't run every app.
