The E815 was by far the best MOTO i have had,the service was fast,screens were faster and no waiting for anything. The krzr on the other hand i am not as impressed with,it is slower,more annoying to text n takes longer to load. Now when i start to mess around and IF i start to mess arouns with the firmware then i may say different,but all in all it would be noce to have the krzr with the E815 internals. I ma just waiting for the Motorzr MAXX to come out hten the KRZR is going on e-bay. As far as ur vast knowledge of firmware on motos logic…u have none…
