When was the last revision to the iBook line? My wife and I have agreed that we want to augment our current Mac with a 12" iBook and an AirPort Express Base Station. I have no memory of when the last revision to the iBooks happened and I don't want to be one of those "lucky" folks who buys only to have a better model come out a couple weeks later. Also, knowing utterly nothing about graphics cards, can someone tell me how the ATI Mobility Radeon 9200 in the 12" iBook stacks up next to the GeForce2 MX that I currently have in my iMac G4? Presumably, it's a better card, right? I don't want to assume because I know that laptops sometimes have to be hobbled in strange ways in consideration of heat issues and it makes me wonder how this card performs.
