Well here is what I have decided to do.
I am waaaaayyyy too impatient to wait for weeks to get a refurb Mogul, as attached to that phone as I was. After reading a lot about the Touch Diamond, the only two drawbacks that I can see are the lack of sliding keyboard, and the lack of additional storage capacity (4GB internal only).
That being said, it looks and feels like a nice phone and has a good form factor. I see there are apps that I can load that will limit the keyboard shortcoming by giving a reasonable touchscreen keypad. Since my only option is to choose the diamond or wait as eternity, I will choose the diamond.
I hope that I do not regret it
