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!"
ive never been in a car where these cigarette lighter adapters stay in place. sure, they stay put for a week or so, but then they wont stand up straight and eject your ipod/iphone every time you go around a curve. no thanks.
