Ok, I should hopefully be getting another 'book tomorrow for the girlfriend, a G4 1.2 from which the seller's removed the hard drive. Now I'm trying to keep costs down as she can't afford much. This will become her only computer, going from a Dell desktop with I think an 80GB HD. The G4 will be 1.2Ghz w/ 768MB RAM and a Combo drive. The choices are: 60GB 4200rpm drive for £42 (£0.70 per gb) 60GB 5400rpm drive for £46 (£0.77 per gb) 80GB 4200rpm drive for £45 (£0.56 per gb) (Refurb) 80GB 5400rpm drive for £54 (£0.68 per gb) 100GB 4200rpm drive for £65 (£0.65 per gb) 100GB 5400rpm drive for £68 (£0.68 per gb) Now I would want this puppy to last a good while for her. She has lots of space left on her Dell (well she says so at least) and I can imagine most of her stuff is music (hours of wmas I'm going to have to convert). To be honest, I'm leaning towards the 5400rpm drives because 4200rpm is *sooo* yesterday although that 80gb 4200 drive is sure good bang for buck and like I said, we're trying to keep the costs down. What do you guys think?
