Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
Trend definitely seems to be favoring square-cornered clamshells... and diminutive external displays. Me likey! Longer battery life. I don't really need to have my cat's picture grace some fancy large exterior color display.
To think the Samsung m610 was knocked for it's "small exterior display"... in comparison to these phones, it's gi-normous!
