The motorola droid is an amazing phone. I remember when we were awaiting the Dinc, we would take pot shots at the "old" droid as being clunky and underpowered. However, like the Dinc, it still is one of VZW's top selling, high-end, highest price phones.
If you had bought a Droid, you wouldn't have made a mistake. It's a great phone. If you purchase a Dinc, you would not be making a mistake. If you purchase the X you won't be making a mistake. They're all great phones running a great OS. Me? I want the 1ghz processor as I tend to use my phone heavily and multi-task a lot. Others may want the 720p recording and the bigger size. To each his own.
I assure you, however, the Dinc is not a cheap toy. It is a sophisticated piece of tech. So is the Droid. So will be the X. Honestly? So is the iPhone. Had it been made available to VZW before I got Android savvy, I would have bought it. I got wiser, however. I had grown to detest Steve Jobs and I'm one of you, now.
Somehow, I think that if you can put down another phone, it makes the one you have or want better. The dinc is fantastic. It is a great phone. The variety we now have makes your choice both difficult and sweet. Enjoy the dilemma.
