Hi, I'm jc, longtime viewer, first-time poster. I have a dilemma. I need a new computer, and have narrowed it down to a PowerBook 12" with SuperDrive. And so, I have waited since WWDC for some sort of PowerBook update, to no avail. My second choice was a 17" iMac with SuperDrive, and it is looking better and better with the Massachusetts tax holiday on Sunday. So, what should I do? Am I being stupid to believe there will be an update to the PowerBook (7748?)? Should I get the current PB, wait for an update, or just get the iMac? Suggestions?!
