Apple should move to Magnesium for its case.

    There is one big advantage to magnesium that is the strenght to weight ratio. They could greatly reduce the weight of the ipowerbook if they moved from aluminium to magnesium. I don't understand why they still use aluminium when there are better metals to use.

    Magnesium is very reactive?

    Won't magnesium be more expensive than aluminum?

    PowerBooks used magnesium frames years and years ago.

    Not really, they're pretty close.

    Well, isn't a MBP already more expensive than other PCs using titanium and other superior materials? It is not too much to ask for isn't it?

    But they have an Aluminium outershell and using magnesium outershell would make things lighter.

    They do use a magnesium core surrounded by super high strength Plexiglas on the ibooks)have for 4+ years. Whats magnesium strength to thickness ratio? Could this be the reason its not used on the super-thin pro lines? Or maybe anodized aluminum looks cooler and doesn't need to be painted(remember Ti books) Also the difference in atomic weights is 2.7 with magnesium being 24.30 and aluminum being 26.98. Thats a 10% difference. To make magnesium stable it is often alloyed with aluminum further negating this difference. We are talking grams in something that weighs over a kilo. I am sure apple throughly looked into magnesium and choice anodized aluminum for some reason.

    It's kind of meh, especially with thin stuff. Mg has a tendency to be brittle, so you end up mixing it up with aluminum anyway. It works better in thicker parts like cast frames. Another problem when it comes to Apple is that the metal tends to have kind of a brutal looking finish, they'd want to paint it or go with a plastic casing :(

    What I'd really like to see is a return to the TiBooks, or black/grey carbon fibre..

    "a more sinister and darking looking MacBook Pro..."

    I like the sound of it already :)
