So since the Intel switch I have recommend the Apple MacBook as the best choice laptop for all sorts of situations.
It still offers a stable, Tier 1 build quality, the advantages of the OS X, the ‘i’ apps and looks good.
However with the new release models there has a been a number of significant changes and not all for the best.
The Firewire 400 ports have been removed from all the laptops and only a single Firewire 800 port remains on the MacBook Pro.
In terms of music production this is a major problem as compatibility has been lost with many pro-grade soundcards for the MacBook such as the MOTU 828. Its also bad news for video people as well.
At the moment I am not sure what to suggest; the MacBook Pro is more expensive and is bigger mmm I will have a think.
You can find the MacBook specs at http://www.apple.com/macbook/specs.html.
