Regarding the first one, I don't think this would be a serious issue. It shouldn't show what move its considering, just the current best option. It would probably converge on a good move within the first second. Running the free, quick analysis from chess.com on my Iphone has a great visualization that rapidly updates the computer's scoring of the current position and shows what it thinks is the best move, as well as pointing out any previous moves it thinks are mistakes/blunders.
