My dad, who recently bought a Macbook, is planning on letting my mom have the Powerbook G4 that it is replacing. After talking with him a bit, I found that he is interested in trading the Powerbook for my iBook, as the increased portability, durability, and battery life would really suit her more. I am also interested, but I would like some input on the performance difference between the two machines. My 12" iBook has a 1.33 GHz G4, 133 mHz system bus, 1.5 GB RAM, a 40 GB 4200 RPM drive, and a 32MB Radeon 9550. The 15" Powerbook has a 1 GHz G4, 167 mHz bus, 1.25 GB RAM, an 80GB 7200 RPM drive, and a 64 MB Radeon 9600. I use my laptop for a fair amount of gaming (Warcraft 3, Neverwinter Nights, World of Warcraft), and I'm just curious if the increased bus speed, doubled VRAM, and faster hard drive are enough to more than make up for the 33% slower processor hit (pretty significant when dealing with speeds that low), 256 MB less RAM, and slightly higher native resolutions I'd be dealing with. I love my little iBook, but I'm willing to trade if I can see a noticeable improvement in game performance.
