I thought I would clue people in on a little Microsoft scam going on with the new Premium 360's that have HDMI. If you use the HDMI cable and have a separate audio hookup (surround sound or optical audio) you will need this...

And it costs $50.
If not, you will only be able to use the audio from your TV when using HDMI. Essentially, when you use your HDMI cable you override the normal A/V jack in the back of the 360. It is "shut off" when the HDMI cable is active. You need the audio adapter included in the $50 set to use an outside audio source.
By comparison, the PS3 allows you to use the standard A/V cables for sound, while using an HDMI cable for video. Obviously, Microsoft is trying (again) to nickle and dime the uninformed consumer.
If you buy an Elite (as I did this past weekend), the HDMI cable and precious audio adapter are both included. So I guess this is one more reason to buy an Elite if you care about such things.
