Powerbook G4 vs. Early 2006 MBP

I currently own this 17" Powerbook G4. I'm wondering what you guys think about selling this and purchasing a MBP (off of craigslist) with that same money. It is
15.4", 80G HD, 1.83 Intel Core Duo processor, and I haven't asked him how much memory is on it yet ..

Anyway, the specs of my Powerbook G4 are as follows (taken from the craigslist post I bought it from)

G4 processor at 1.67 Ghz
2GB DDR Memory
120GB Hard Drive
Dual Layer Superdrive
256mb Vram Ati Pro Graphics Card (Quartz Extreme Supported)
2nd Display Support: Dual/Mirroring
Max. Resolution: 1680 x 1050


Do you think it's worth it to switch over? If you can tell me why or why not .. COOL!

thanks in advance ..

It is mainly because of the processor? I mean, I guess I don't need the "BEST" right now but maybe if there is a HUGE difference and worth the upgrade if anyone is willing to convince ..
