I've started a new section for Xbox 360 hints.  These will just help people learn more about their 360 to get the most out of the system.  My first hint will be you can Boot to Dashboard.  The 360 default so that when you turn it on you go straight to the game in the DVD drive.  Well with the Spring '06 update you now can start your 360 and always go to the dashboard.  I mostly do this because I like to see who's online first and maybe browse the Marketplace for new demos and trailers.  To enable this go to the Systems blade and pick Console.  Scroll down to Startup and click it.  Then select Dashboard as your default option.  I'm surprised the Dashboard isn't the default because it's so nice to just turn on your 360 and not go straight into a game.
