Gee,
There is a current and limited ability to burn HD content on the Mac with Toast 10 Pro.
And, if someone was using a cheap LCD monitor (or HDTV), like a Dell SX2210, which has DVI and HDMI, they could use their Mini for general purposes via the DVI and connect a cheap HDMI Blu-Ray player to the monitor, too, for watching commercial Blu-Ray DVDs. Although, it would be nice if there were some more compact-styled Blu-Ray players that had HDMI.
I mean, that's a tack I'm currently looking at, in an effort to combine computing and multi-media into one potent little package.
Or, I may just connect the 2009 Mini to a 32" Toshiba Regza for a monitor via a PC/VGA connection, which is what it likes better than trying to go through HDMI. I currently have a PPC Mini on the Regza, as a music and music video player with iTunes and for web browsing with a lap-style RF keyboard/pointer. But it just doesn't seem fitting to use such a big screen, and use VGA, along with the distance that is needed to do computer work. Plus, I'd rather use a wired keyboard on a desktop surface for computer work.
So, who knows, maybe I'll get rid of the TV, and get a compact little El Gato tuner for the Mini and a monitor, so that I can do it all in one place, yet still create a smart blend of an entertainment center and desktop area.
Peace to you all,
