Bare Feats has published a performance comparison between the recently introduced PowerBooks and Power Mac G5s. “Steve Jobs asserts that laptops will soon replace desktops. I assert that ‘heavy lifting’ will continue to be done by desktops, especially ones with dual processors,” reports the site. “The PowerBooks lag significantly behind the newest desktops. If you need a ‘professional grade’ computer that can get things done in a hurry, you better hope the PowerBook isn’t your only computer.”
