I know of all the technical differences between the two, but I do have a few questions. Right now I'm leaning towards the Macbook, but if I'm wrong about a few things, I may go with the Pro instead. 1. I've read the Macbook has 5+ hours of actual battery use, while the Pro averages 3-4. Is this true? 2. Does the Pro get much hotter than the Macbook? The main reason I'm getting a new notebook is for the portability and I plan on typing up school papers while on my bed, or laying back in a chair, so I don't want issues with the notebook getting too warm on my lap. 3. I know the Macbook is lighter than the Pro, which is potentially a big deal to me. But it's only 1lb difference. That sounds like a small difference, but sometimes even 1lb and other physical dimensions can make more of a difference that one might expect. I don't live near an Apple store, so I can't check this out for myself. Is the Macbook noticeably more comfortable to carry around and use on your lap? I'm not worried about 5.5 lbs tiring me out, but it does sound like it may have the potential to be uncomfortable. Now for some general questions: 4. I know both screens are glossy. Is it possible to use these notebooks outside? 5. I'm a college student majoring in English, so I'm always typing papers and creating presentations, especially Powerpoint. iWork 08 seems like an obvious need. Is it an acceptable program? I appreciate any input. Thanks.
