is there likely to see an aluminium macbook any time soon ?
No.
Aluminum would reduce the weight of the macbook too much. The MBA would become nearly unsellable (why pay $1800 for a 3lb laptop when you can get a 4lb or less laptop for $1100).
In addition, aluminum has been the hallmark of the "pro" notebook series for quite a few years now. Plastic has generally been reserved for the "consumer notebook" like the iBook and Macbook.
Apple doesn't like to change pricing too often, so if the macbooks ever do see aluminum, I'd imagine them staying the same in pricing (though that could change if they are dramatically revamped-though I don't think that's going to happen).
and something else; what is your best guess for the Ghz in the
next Macbook update ? will we see 2.4 Ghz any time soon ?
They have to be less than or equal to the mbps, so use this as your metric.
Otherwise, only time will tell.
Aluminum MacBooks will probably come out in the summer.
Based on what?
MacBooks are the only plastic Mac products left.
Except for the Mighty Mouse, Airport, or any number of smaller Apple accessories right?
And if Apple wants to get on GreenPeace's good side, they'll have to get rid of the plastic.
I think you're referring to PVC, which the macbook case is NOT made of. PVC is an internal component, not a component of the case.
Unless Greenpeace has some new demands.
I wouldn't be surprised to see many color choices, like the old iMacs or current nano's either.
A colored MB actually sounds fathomable
You mean like Clamshell iBooks?
I think Apple is done with that. iPods are different because they're small and don't represent the Mac lineup.
