Amazon might still make most of its money by shipping physical items to your door, but it's clear that the retail giant knows the future of media is digital -- not only is it pushing the Kindle and services like Amazon Video On Demand, it's expanding its downloadable video game catalog to include Xbox Live Arcade games today. The process seems a little clunky at the moment -- you buy a code from Amazon that you have enter into your Xbox -- and it's not exactly easy to compare prices, since Amazon charges you real money instead of Xbox Live points, but we're not going to complain too much about anything that increases gamer choice. (Using real money actually seems like a benefit to us -- we've never really loved the idea of points.) The service is live now, anyone going to do a little shopping?
