When I first saw this title |シアワセ ナ オススメ - HAPPY RECOMMENDERS -| on google I just whent and bookmark it. Hands down, Apple's app store wins by a mile. It's a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I'm not sure I'd want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.
