My new 17" Core 2 Duo iMac, sitting next to the MacBook (although the MB is just on my desk for the sake of the picture).
The iMac is the entry level one with 512Mb and GMA but I don't play that many games and I will try and bump the RAM up next week. It's replacing an old 1.25Ghz Mac mini which I finally got fed up of when it was taking 3 minutes to load iTunes 7 with my music library! It's sitting, without a display, keyboard and mouse, connected to my router so I can get files off it.
I was going to get another Mini but then I thought for a bit more cash, I could get an iMac so here we are! It didn't come with the Apple Remote, but the one that is stuck to the iMac is from my MacBook - at last somewhere where I won't lose it!!!
Sorry for the bad picture, cameraphone.
