This week the Motorola ATRIX HD has been revealed for AT&T's 4G LTE network with a massively high definition display and a dual-core processor under the hood. This device enters the ranks of the top 10 highest-definition display-having devices on the market at 329 PPI, only being beaten by the HTC Rezound, Sony XPERIA S, and LG LU1400 (a strange swivle-screen smartphone from 2008), and matching the LG Nitro HD - and yes, it beats the iPhone 4/4S. That's 1280 x 720 pixel resolution over a lovely 4.5-inch display that Motorola touts as 720p HD ColorBoost.
This device is rather similar to the Motorola RAZR in that it looks the same, sort of, and is thin at 8.4mm - while the RAZR was (and is) just 7.1mm. The thinnest smartphone on the market today is the ZTE Athena at 6.2mm. Of course being part of the most recent Motorola line, it's ultra-thin but not breakable (with any normal human means) as its made with DuPont Kevlar fiber on the back, splash guard coating on the outer shell to make sure you're not getting wet as well as on the electrical circuit boards inside. Corning Gorilla Glass covers the front for ultimate scratch resistance as well.
The ATRIX HD works with Motorola's newest software build on top of Android 4.0 Ice Cream Sandwich, and Motorola is touting a cool new "Motorola Circle Widget" with "at-a-glance" access to your notifications, time, weather, battery, data usage, and settings. You've also got a feature/app called SMARTACTIONS that will allow you to change your phone's settings based on certain situations and/or times of the day.
The back-facing camera is 8-megapixels and 1080p video while the front-facing camera has 720p video. You've got a microUSB and microHDMI port with easy mirroring abilities for your HDTV. This device also has CrystalTalk PLUS noise reduction which, in part, comes from its 3-mic setup, and it's got 8GB internal storage and a microSD card slot to boot.
Finally, for carriers you've got AT&T with 4G LTE as mentioned above as well as Bell up in Canada - pricing and availability for Bell will be announced soon, while the AT&T version will cost you a cool $99 USD on a 2-year contract.
