Open Source: Why Apple?

Apple and open source? I don't get it yet, but apparantly if you want to be taken seriously in the open source world you need to have at least an iBook.

Is it just the not-microsoft sentiment or is there a more rational reason for its popularity?
For one thing, most open source developers are either smaller companies are people working in their own time. So corporate company standards don't apply, and there is a choice.

Given that we have a choice, why do we choose the mac. For one thing it is unix underneath. So it has all the unix tools developers are accustomed to.
We also have an apache server and cvs out of the box. So compared to windows there are defintely benefits.

But compared with linux?
