Received my base model mac mini last night. Synced Apple BT Keyboard and Mighty Mouse Connected a lacie external HD and Dell 2209WA monitor. The mac mini will be my base station for itunes to stream to the appletv. First thing I did was add to the itunes library my music/movies. This was a painful process took forever 2hrs. I think this might be because of the limited memory 1GB. After its all said and done though the mac mini runs smooth and streams without stutter to the appletv. I installed parallels and running windows xp. Here I can definitely tell a difference from my macbook pro. It reminded me when I only had 2gb in my macbook pro. I think 4gb I will see a big difference in my mac mini. Definitely will buy memory and a new harddrive (maybe on the harddrive) Just hate to open it up.
