Amazon introduced a new line of Kindles yesterday, all likely to rock the tablet market, as they’re priced unbelievably lower than competitors’ prices.  The online retailer unveiled two new e-readers and three new tablets.

E-readers

.

Kindle Paperwhite and Kindle Paperwhite 3G are the same, except the 3G version allows you to access the internet without a WiFi network available as it connects to Amazon via 3G at no extra charge.

Both devices feature a 6″ Paperwhite display with patented built-in light, 212 ppi, optimized font technology, 16-level grayscale.  The screen of the devices are matte so you won’t have to worry about glare when reading in bright places.  The built-in light is great for indoor reading, as it shines on the print, unlike regular devices where the lights shines from the back and hits your eyes, making reading uncomfortable.

They’re both fully wireless, so you don’t need a computer to download content from Amazon, and you have free cloud storage for purchased Amazon content so you don’t have to worry about your Kindle Paperwhite becoming full until you get to around 1,100 books.  The devices charge completely in four hours when connected to a computer via USB cable, and can last up to eight weeks without charging, but that depends on how much you use it and if WiFi and the light is on.

The Kindle Paperwhite costs $119 while the 3G version costs $179.  If you want to spice things up, you can add color to your device with a variety covers that lets your device sleep when you close it, and automatically wakes it when you open the cover.

Tablets

Amazon’s new tablets include the Kindle Fire HD, Kindle Fire HD 8.9” and the Kindle Fire HD 8.9” 4G LTE Wireless.  The tablets are almost the same except for some minor differences, like the size.  The Kindle Fire HD is smaller at 7” and the two 8.9” tablets are the same except one is 4G.

All three tablets feature an HD display with polarizing filter and anti-glare technology for rich color and deep contrast from any viewing angle; have exclusive Dolby audio and dual-driver stereo speakers for immersive, virtual surround sound; dual-band, dual-antenna Wi-Fi for 40% faster downloads and streaming; 1.2 Ghz dual-core processor with Imagination PowerVR 3D graphics core for fast and fluid performance; access to over 22 million movies, TV shows, songs, magazines, books, audiobooks, and popular apps and games such as Facebook, Netflix, Twitter, HBO GO, Pandora, and Angry Birds Space; integrated support for Facebook, Twitter, Gmail, Hotmail, Yahoo! as well as Exchange calendar, contacts, and email; free Skype video calls with front-facing HD camera; and free unlimited cloud storage for all your Amazon content.

Amazon is also introducing a new feature next month called Kindle FreeTime, which allows parents to put restrictions on the tablets without any hassles.  Kindle FreeTime is a free service on every Kindle Fire HD devices and it would allow parents to create a profile for each of their children and choose what books, apps, games and videos they want to give their kids access to.

The service allows parents to enforce screen limits, so they can set daily caps on how many hours their kids can use the device each day.   And because the Kindle Fire HD series was built with kids in mind, you won’t have to worry about accidental bumps and scrapes, as the display is 20 times stiffer and 30 times harder than plastic.

The Kindle Fire HD is available in 16GB and 32GB version at $199 and $249 respectively.  As for the 8.9” Kindle Fire HD, it’s available in 16GB for $299 and 32GB for $369.  And the Kindle Fire HD 4G is available in 32GB for $499 and 64GB for $599.
