Got a tough choice and its too close to call... go for a used 1.83/2.0GHz macbook and get the speediness of intel but the bad graphics, or a high end 1.67GHz/1.5GHz PB g4 15"/17"? Im guessing the powerbook would be better for light gaming due to the dedicated graphics but the macbook can run windows and is more modern. very hard choice your input would be much app.
