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!"
The Premium at 349 is alright but the Core is pointless and should be discontinued.
I returned my Premium via Best Buy Replacement for a $428 Gift Card. Went and got a Brand New PS3 60Gb for $425 out the door.
I love Xbox but how can I justify an Elite @ $450+Tax after a deal like that!
