While waiting for BB to eventually get the Verizon V20, I do not see the practical value yet of the second display and see it as arbitrary. Current perspective though is just based on my brief use of the device in a carrier store.
It gets in the way with some games (portrait mode)
Can accidentally be triggered (flashlight is first thing to remove from it)
Wastes bezel space. Would have preferred shorter device or front stereo speakers (this)
Uses power (based on review tests, 1% to 2%)
Edit: No calculator? WTH?
It seems to do nothing much that can not be dragged down to use, or from status bar. A main thing touted is the music app, but Power Amp already does a similar thing in status bar.
Hoping my perception changes from thinking it is an overall negative in relation to the items noted above. Catch is have to be able to get one first.
