I can claim for sure you never touched a Motorola Droid 4 pichlo, its slider is incredibly bad. With the N900 I give it one quick push with the thumb and it clips into the open position. One quick push with my index and its closed. With the Droid 4 I have to force it all the way up, and it constantly changes in resistance on the way. To close it I need to use thumb and index of both hands. And that describes the better one of the two i own.
