Hello, Our 20" iMac arrived today. Mega stoked it came, and only took a week to get here from Shanghai (BTO). It does however have the gradient issue on the screen, which isn't a problem for the uses it is getting. However, does anyone know Apple's take on this? It came pre-installed with Leopard, which is nice in one way, but I was hoping for Tiger because I prefer using it. Whatever I guess. It is such a massive screen, even being only the 20" and I am seriously happy to have made the purchase. It replaced a very very worn out Dell desk top computer and is an addition to my 17" G4 PowerBook. Another point you might be interested in, when I ran software update, I didn't have download the firmware update for the graphics card. So it is installed on the machine. Let's hope it is a freeze free iMac. Alex.
