I have recently bought a 27 inch imac but found that even with the imac and my ipad i missed having a true laptop....i found a good deal on an ibook g4 (85.99 shipped on ebay) its a last gen 1.33 ghz with 1 gb of ram the 12 inch model....and actually im really enjoying it but was curious how much better a last gen powerbook g4 would perform in relation to the ibook....i like the 12 inch form factor but could possibly lean towards a 15 inch....
