I got the Droid X the first day it came out. First one died last month (was a very good phone) due to a software issue. It just went into a continual reboot cycle. Got my 2nd DX and its buttons were loose and the volume button up was super stiff with no tactile feedback. Now I am on my 3rd DX and it is always so laggy and the buttons are even worse now. The volume rocker doesn't feel right. I don't want to get another replacement for the DX as I am sick of getting defective ones. Is there anyway I can get a different model do you think? What does VZW consider equivalent to the DX?
