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!"
That's too funny, because as the 29th gets closer, the specs on the iPhone diminish. No MMS (incoming OR outgoing). No Flash. No real 3rd party applications. Tied to a single service provider in the U.S. Tied to using iTunes (though the Apple faithful won't mind this, those new to the cult may find it to be a problem).
Just wait for the threads and posts and blog entries to start popping up early in July, after the product has reached the masses. I'm betting a good deal of them will be less than glowing once reality shows up at the party.
