There are differences in the powerbook line itself. But if you are comparing the 15" powerbook to the ibook, then there are several differences, Any time I refer to powerbook it will be the 15" models here.
The motherboard on the powerbook is 167 MHz vs 133 MHz in iBook. The memory in the Powerbook is DDR 333 vs DDR 266 in the iBook. The powerbook can support up to 2 GB af RAM the iBook supports up to 640 MB.
You can get the Powerbook with a Superdrive installed for burning DVDs, this is not a built to order option for the iBook. The powerbook can have a faster processor if you order the higher-end model up to 1.25 GHz the iBook line is up to 1 GHz. The powerbook has 512 KB of level 2 cahce, the iBook has 256 KB of level 2 cache. The powerbook has a PCMCIA slot for expansion, the iBook does not. The powerbook has the ATI 9600 with 64 MB of DDR RAM, the iBook has the ATI 9200 with 32 MB DDR RAM. The powerbook has a built to order option for a 5400 RPM harddrive, the iBook does not. The powerbook supports higher resolution than the iBook.If you go with the higher-end 15" powerbook the harddrive is larger than the iBook and the powerbook will have the backlite keyboard which not available with the iBook and the Airport Extreme card will be included. The powerbook has a ultra ATA 100 hard drive, the iBook has ultra ATA I beleive only 66, but am not sure. Obviously the powerbook has a larger screen, and as mentioned before has firewire 800 which is not available on the iBook. Powerbook has DVI and s-video out, iBook is VGA and s-video out with adaptors. The powerbook has audio line in, I do not think the iBook does. I think that is about it as far as hardware. A bunch of differences.
