Howdy all, I'm a few days away from buying my first Mac ever, which seems a bit strange after using every Microsoft OS since 3.1. Anyway, I need some advice. I want to buy a 15" powerbook, but need to choose between three: 1.5Ghz, SuperDrive, 1 Gig of RAM, 64MB Vram - AUD$3400 1.67Ghz, SuperDrive, 1 Gig of RAM, 64MB Vram - AUD$3700 1.67Ghz, SuperDrive, 1 Gig of RAM, 128MB Vram - AUD$3800 I guess my question is pretty simple, is it actually worth the extra AUD$400 (US$300) for the slightly faster processor and more Video Ram. I know on the PC video ram is normally only needed if you want to play games, etc - which I don't want to do. I just want a good laptop for video editting and working with photos, etc. Also does the extra hundred or so megahertz of processing power actually make any practical difference? Is there any 'hidden' differences betweent the 1.5ghz and 1.67ghz powerbooks? Does the 1.5ghz run any cooler than the 1.67ghz? What about battery life? Anyway that's all the questions I have, I know there's quite a few in there, but these are all things that are pretty foreign to someone coming from a PC background.
