i think that the standard wp7 metro ui it already complete and doesn't need label for icon, because they are already "explicit" for the target, adding label it's a duplication of information (label + icon) and result it's an heavier ui...
i'd like having the ability to change te background color of every tile, having the possibility to set a gradient, and the main background.
i think that it's only a matter of time that wp7 is released and we become familiar with the new ui and os
