I am the most excited about the mention of the resolutions; in the past you would have to use a third party product such as DisplayConfigX to get your Mac mini to output the correct resolution, now it seems it's supported by OSX. This in combination with the overscan adjustment built into to the display preferences is very impressive. Audio was considered as well as the new Mac mini includes SPDIF in and out so you can enjoy DD 5.1 in all it's glory.
Now all we need are HD movies via iTunes and life would be perfect. I am of course assuming that the Core Solo 1.5 is fast enough to decode H.264 HD material. Even though I just got my MacBook Pro I am off to Apple.com to order a new Mac mini!
