Review: Motorola Atrix HD for AT&T
The Atrix includes the stock Android browser. The controls are easy enough to use and the browser does a fine job of rendering both full HTML and mobile-optimized web sites. When used on AT&T's HSPA+ and LTE networks, the experience is quite good.
Browsing speeds felt Porsche Boxster fast on the HSPA+ network, but ramped up to Porsche 911 S speeds when using AT&T's LTE network. Most anyone will be satisfied with the performance of the Boxster, but once you get a taste of the thrill offered by the 911, you'll never want to go back to the Boxster. This is why we wish AT&T's LTE network had a bigger footprint. It's certainly growing, but it doesn't yet match what Verizon offers. I still have to drive about 20 miles east to find LTE coverage, and I live in the metro NYC region.
As I've noted in other reviews, Google's Chrome browser is a better option. It's not any faster, but the tools and features are far superior to the stock Android browser.
I'd rate the Atrix's customization powers as about average. You can add and delete home screen panels at will, stick all sorts of widgets, apps and shortcuts on them, and do all the normal things such as change-up ringtones, wallpapers, and such. It doesn't offer items such as different themes and you can't adjust the lock screen shortcuts. Most users will be happy with what they can adjust, but some power users may feel a bit limited.
