ig88, I agree with you about the convenience. I'm still not seeing where this CardBus slot is on the PowerBook G4. I think I've pretty thoroughly searched the exterior of my unit. Is it buried behind the keyboard or something? (The WiFi card slot was there on the G3 model I used to have.) I don't think that would work too well for a CF adapter.
Oh, wait-- I have the 12" model. I bet that's the difference. Is it only on larger models?
