I have read some things that seem to indicate the Xbox 360 does a poor job of playing HD-DVD movies, which is disappointing. I had considered keeping my HD-DVD drive and getting an Xbox to play the movies. I think the best solution is a PC because you can easily switch formats if one fails. I am not a PC gamer but I would like to check out some DX10 games also. I have been very impressed with the trailers I have seen.
