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!"
Another feature I like is the music player, and control buttons on the outside. Replaced my IPOD with this phone while jogging, so I have less to carry. Holds massive amounts of music, and I don't think I can fill the memory even with the hundreds upon hundreds of MP3s I have. Easy to use and sync.
