Here is my new Mac Mini Core Solo. I am quite happy with it since it is very quiet. It makes a good jukebox/movie/server machine. Apple was very quick in shipping it (2 days)
However I was a bit disappointed by iPhoto 6, it is not as nice as Picasa to sort out pictures (no IPTC support). I did not try Java on it yet. I just found out my little Benham circle applet was not working properly on it.
