I can't even begin to tell you how much I enjoy using Amazon's latest Kindle Fire tablet, the HDX  8.9.
It's amazingly light (13.2 ounces, not even a pound!), fast (a 2.2GHz Snapdragon processor), with a responsive touch screen and great screen quality. Plus it has goodies like front- and rear facing cameras, surround sound, and the battery lasts forever. It's a joy to play with.
But for the past few weeks, I've been trying — mostly unsuccessfully — to use this tablet for work, not just play. By work I mean email, creating and editing documents, backing up documents to Amazon's built-in cloud service, and sharing them with my main work computer, a MacBook Pro.
I've been testing the Fire HDX as a work machine because Amazon has added a whole bunch of enterprise-friendly features to it, like support for corporate email, a bunch of security options and, most importantly, the ability to share documents with my work computer via the cloud.
Amazon upgraded the HDX to go after an area where the Apple's iPad has been killing it: work tablets. Over 90% of tablets in the enterprise are iPads and nearly all Fortune 500 companies are using iPads, Apple's CEO Tim Cook says.
That's a potentially huge market for a Kindle with its low price, $379.
