All was wonderful when I got it home, until I tried to connect it to my Wi-Fi network, which not only failed but I managed to knock the whole network off the air trying to fix it. I was terribly distracted while we went off to our neighborhood SF book group (this month's book: The Year of Our War, which we all thought was a bit shallow and the main character unsympathetic), but when we got back I used the DSL modem's setup disk to reinstall it from scratch and all is now cool.
Spent the rest of the evening installing Tiger. Now I'm back to where I was Sunday when the DVD drive failed. At the moment the new Mac is downloading software updates, and I'm going to let it have fun by itself, for I must sleep now.
