will the operating system be a version of os x? will G3 processors still exist in the ibook or will it have a G4? will there be a G5 powerbook? will the G5 desktop reach 3 ghz? will apple make a cell phone or pda? how about lower prices on some items like the 17" inch iMac, the ipod, or the entry level G5? will the 14" inch ibook survive? how about the titanium exterior on the tibook...could it go to aluminum? ....thoughts?
