In WP8, Microsoft got rid of the right side vertical gutter, thus allocating more space for the Live Tiles. However, there is still an unused black gutter at the top just - underneath the clock area and between the first row of Live Tiles. I was looking at the Lumia 920 and it just stands out more (at least to me) because of the larger screen size. So I looked at the Samsung Focus and realized that it was present even with WP7 devices. Does anyone know what this black bar of nothingness is for? Is it a placeholder for future functionality? Is it just for design? Future Notification pull down area? Is it currently being used in WP8?
