If you compare the S3 vs the DRM, you'll find that each has adv and disadv. Overall specs would have the S3 being the better phone, but does it make it a better phone?
Sure you have quad core processor. What apps is really going to use QC? The only thing QC is going to do is drain down your phone faster, which it will certainly do with the S3.
I'm going to stick with my DRM. I bought for one main reason: Battery life. I play a lot of golf during the spring/summer and use my golf GPS often. With a regular phone, after 18 holes, I'm almost completely drained. That means if I play again, I can't use the GPS on my phone. The DRM solved that problem. Plus, who wants to buy an extended battery that would make the phone thicker than a brick. The DRM has the extended battery while keeping it very slim. I like that. To me, that is its most important feature.
I could care less about all that other stuff. I've learned my lesson with Smart phones: I've had 4 Smart phones now for the past 6-8 years. Each had its own special features. Each had its own little trick. Each had its own little gimmick. But what it comes down to is call quality and battery life. That's it.
All that other stuff wears out like a cheap suit over time. Stuff I thought was cool the first week, becomes unused, within months.
