"Not quite perfect."2.5 starson by jfrag
Pros: Size is nice
Cons: No Video-In
Summary: The one issue I see is that you have no video-in capability.
So either you have the issue of a PC with MCE not integrating iTunes, or you have a Mini with no "Tivo-esque" capability.
The winner for me would be to continue to use MCE for now, and just jump back and forth to run my m4v files.
