Atrix: (540x940) Resolution
Proud owner of an Atrix myself. What sold me was the Qhd Display (540X940) much higher than standard. What sold me again is its only 4" I wanted it semi small.... anything over 4 is just to big in my opinion. What sold me again is Dual Processor and 1 gig ram. So display, Size, CPU, Ram, 16gb internal storage is nice too. Not to mention the 1930Mh battery. Im no cell geek.. but thats a rather large battery. Only bad thing i can say about the atrix is Moto Blur. Its slower than the HTC sence line. But i mean really... ya cant wait a half a second more?
Infuse: (480x800) Resolution
4.5 Inch.. to big. Atrix has higher resolution ... Infuse has 8mp camera i think... Atrix only 5. But i mean.. you wanna take pics better than 5mb... better off getting a camera. What sold me was.. Smaller package.. but twice the power. And people always complain about the battery....With Atrix... not as many do. Donno if Infuse has a Mini HDMI port.. but Atrix does... Its nice to be able to show videos and pics on a nice LCD flat screen in HD. I heard somewhere that future updates might be able to record 1080P on atrix. Just a rumor. Happy shopping. Trust me you wont be sorry with the atrix
