Let's assume you have an HDTV and a good set of speakers in your living room.
You connect the new Mac mini with a wireless remote control, keyboard and mouse, and an Internet connection, then settle back in your favorite chair and start using the standard Mac applications on the big screen. For example -
* Record and watch television programs with the DVR feature
* Edit and present your digital photo albums with iPhoto
* Play music with iTunes, with realtime visualizations and album art
* Edit your home movies with iMovie and burn discs with iDVD
* Surf the Internet with Safari or Firefox, and send email
* Text messaging and 4-way video conferences with iChat
* Much more...
Since it is Intel based, it should run Windows too.
That is a lot more functionality in a small box than a regular DVR.
I posted that before I saw all the other features the new Mac box offered.
