Had Microsoft not gone with the idea of Live Tiles for WP8 (or tiles at all for WP7), what do you think they would've designed for their newest platform? Also, do you think the current setup of the Start Screen (Live Tiles concept, strictly) is satisfying? Would you have wanted another design? This is not the thread to talk about a missing notification center, a lack of multitasking, etc., but rather a "what if...?" to ponder about the Start Screen itself (excluding the app list), and not the OS's flaws.
