I'm currently writing a full review of the IRIQ for http://www.hometheaterforum.com
. I should have it done in a couple of days. The review will officially be posted there but I may be able to put a copy of it here as well.
At any rate, there's a thread running over there with lots of info regarding the IRIQ.
For some background: I do not work for Microsoft or Madrigal. I'm a H/T nut with a great relationship with my local Madrigal dealer. I was on the list to receive one of the first IRIQs and I've had it about a week now. If you have any questions, please feel free to ask.
