I work for att at a call center and have done alot of research into different phones i prefer android over phones anyday. the main difference between the atrix and the inspire is goes to be the interface. atrix had motoblur which has been getting better from past modiles and the inspire comes with HTC sense which is my favorite so far, the inspire also comes with alot of widgets that are only provided by HTC. the other main difference and its the only different for the acual equipment not the software. is the atrix has a front facing camera for video chat and the inspire does not.
