Apple just announced their new PowerBooks. No big changes, a modest processor speed bump, more options included in standard configurations (like AirPort and Bluetooth) and a price reduction.
It sounds like Apple is struggling with the next generation, not sure what to choose between dual core G4 or G5, and is buying some time in extending the life of an otherwise good but quite old (by computing standards) product line. It feels like they have bought six months, but that's about it.
I was expecting much more than that, but as Apple is constantly pushing the limits of technology, I bet their technical struggle with putting the G5 in a PowerBook is a seriously challenging one (as evidenced by simply taking a look at a G5, and its radiator, in a PowerMac!).
