Jeff Grainbal writes "Apple will be releasing new Cubes at the MWSF on the 8th. The new models will include a base 500mhz G4 processor as well as a new 600 mhz G4 processor. Apparently, Apple is putting dual 600 mhz processors into the G4 lineup and can boost the Cubes which desperately need it.
Furthermore, the G4 Powerbooks are not going to ship with the nVIDIA chips until, at the soonest, February. There has been a rumor going around Apple that 9.1 will not be released due to bugs, but this is incorrect. There remains one bug dealing with the ethernet driver bug. This will be fixed with an update expected to be released within 2-3 weeks after the conference. Please confirm with your other sources whether OS X will be released on the 8th or at a later date. "
