Well, let's do the math: add the $250 monitor to the $1999 PowerBook and we're at $2259... just $49 less than the price of the iMac and the iBook combined. And the PowerBook has a much slower CPU (1.33 GHz G4 vs 1.6 GHz G5), slower bus speed (167 MHz vs 533 MHz), smaller and slower hard drive (60 GB 4200 RPM vs 80 GB 7200 RPM). To be fair, the PowerBook has built-in Airport Extreme, and this arrangement does permit monitor spanning (not something I'm interested in, but it has its place).

Nevertheless, my point is that for a laptop to be a potential desktop replacement, it at least has to be close to its desktop equivalent, and right now, the graying PowerBook line delivers much less capability for much more money than the iMac and PowerMac desktops... so much so that a whole bottom-end laptop, the 12" iBook, can be squeezed in the margin
