Amazon has brought out its next generation Kindle Fires with new models that have greater resolution, faster processors and in one case the ability to hit a button and get help for issues that may be plaguing the tablet.

The company has also started to take the tablet battle into a new space — the enterprise — as it has added what it calls enterprise and productivity features as tablets are increasingly seen as replacements for PCs in the corporate environment.

The Kindle Fire HDX will be available in both a 7-inch and 8.9-inch model and are both powered by Qualcomm’s 2.2GHz quad-core Snapdragon 800 processor, which the company said was 3x faster than what powered its older models.

The company has also increased the pixels per inch to 2560 x 1600 on the 8.9-inch and reduced its weight 34% to 13.2 ounces while the 7-inch model has 1920 x 1200 resolution. The amount of RAM has been doubled to 2GB and they have a new graphics subsystem for faster gaming. There are a host of additional features including longer battery life and improved cameras.

An interesting feature is the “Mayday Button” that is in the Quick Settings. It calls up an Amazon expert on the device who can walk you through a feature or issue. This feature is available 24/7/365.

One area that the company has created a technology that will likely both further differentiate its products and help open new markets is its Fire OS 3.0 “Mojito” operating system that couples the Android operating system environment with Amazon-only features and cloud coverage.

Mojito may be a strong tool for the company to establish itself in the corporate environment where the “Bring your own device” (BYOD) mentality is becoming strongly entrenched. It has a number of features targeted directly at the enterprise including encryption, Kerberos support for intranet access, secure Wi-Fi, and a native VPN client, among other capabilities.

The 8.9-inch Kindle Fire HDX starts at $379 for 8 GB of memory, while the 7-inch starts at $229 also with 8 GB. Buyers can pre-order starting Sept. 25. The 7-inch will ship Oct. 18, while the 8.9-inch will ship starting Nov. 7. There will also be new colored covers that will be available in seven shades and cost between $45 and $70.

Older models have seen their price cut as the new models come on line with entry-level 7-inch tablet, the Kindle Fire HD with 8GB, to $139 from a $199 version that had 16 GB model.

It will be interesting to see how these models compare with the forthcoming iPads from Apple, widely expected sometime next month. The drive for the corporate space could catch Apple unprepared, and it will be interesting to see what Apple’s message will be when it takes its turn on stage. The corporate push is also where Microsoft has been positioning its Surface Pro tablets for some time, and it just recently announced the latest generation platforms.
