So tell us why? All agree the battery on the Max is superior but if it runs out you screwed. The S3 is very fast and has other features. I compaired a Razor (not the Max) for reception and it did not out perform the S3.
I can sum it up in one word.
Reception
Or lack of. Network and wifi reception on the SIII was nowhere near as good as the Maxx or any of my other previous Moto devices. Same situation I had with the G'Nex. One other thing I did not like is that it was very uncomfortable to hold and use one handed. Even with a case. The buttons were down so low that they were really hard to thumb reach and the curved bottom made it really hard to keep a good hold on it. Battery life??? Well that goes without saying. Just nothing about it made me want to keep it and ditch the Maxx.
