very happy with my 12 " ibook g4(1.33ghz/512mb)(P 70k) compared to the 12" ibm x40(1.4ghz/256mb) which is 50k more. faster start and shutdown, much longer battery life(sira siguro yung battery sa x40, 2hrs lang ang battery life!) and feels faster too. cons: very heavy compared to the x40 and less stable movie players available (problems especially with matroska files).
