The "I have too much free time" Question of the Day!

Take a look at this apple comparison page -

iPhone 5 vs iPhone 4s vs iPhone 4


1) Why do you think they chose stocks as the new app to display on the homescreen?

2) Why do you think they didn't fill the bottom row?

My answers:

1) Stocks sounds professional, so why not?

2) No clue. I'm a bit weird about empty spaces on homescreens, but I also like symmetry. Therefore, I either have all my rows filled or I leave a row completely empty. If the bottom row would squeeze to the center the way the dock does I would be very happy.
