It would be great to know what made DX owners come to the Fascinate & it would be great to know why any Fascinate owner leaves for the DX, or even the DInc for that matter.
I had the DX for about 3 weeks. It was my first smartphone. There were a lot of things I liked about it. But, there were a number of software issues that I wasn't prepared to live with for the next two years and neither VZ or Moto could guarantee they would be fixed with the 2.2 update and they couldn't say when that update was happening. My 30 days was coming to a close and I wasn't willing to gamble, so I returned the phone. Honestly, even beyond the issues, I never quite felt comfortable with the DX - it felt big and bulky for me. But that was just me. It is a very good phone.
I learned that the Fascinate was going to be launched and started researching it. Once it was released and I could actually hold one and test it out in the store, I knew it was much more to my liking. Yes, it has its own share of initial bugs, but these are ones I can live with. And, I know it really isn't much smaller than the DX, but it just feels so much more comfortable and lighter in my hands. For me, it is just more user friendly.
