According to the latest statistics, 60% of XBOX 360 users are using XBOX Live. That is a dramatic increase from the 10% attach rate with the original XBOX console. Of the 60% that are on XBOX Live, 75% use the XBOX Live Marketplace where over 30 million downloads have taken place. 65% of connected users visit the XBOX Live Arcade where more than 5 million games have been downloaded.
This is not really THAT much of a surprise. It’s a great service that just keeps getting better as time goes by, in my opinion. Hopefully it will keep up that way.
