When I originally ordered my S3, I was only planning on keeping it until the RAZR HD was released. But now that all of the specs have been released, there's no compelling reason for me to switch. There's really nothing that it offers above the S3, and there are several things that the S3 offers that it doesn't have. Plus, by the time the RAZR HD is released (whenever "before the holidays" will end up being), there's a good chance that we'll have some other devices to choose from that will actually offer some sort of noticeable improvement over the S3 (something the RAZR HD fails to do in my opinion).
So, nope. Not me. If Motorola and Verizon had released it during the summer, I definitely would have jumped on it. But as it stands, and especially with the release date being several weeks, if not months, away, the RAZR HD is just too little too late for me.
