Do we need a Business & Economy section?

I wanted to post a topic on APPLE computer's new
OS X and its effect on Microsoft and in the business
community.

Or that Can Apple compete with Microsoft since
Internet equalized some parameters?

Where does that go?

That would fit OK into world affairs I think.

Agreed. World Politics OR Technonerds, depending on whether you're going for a general or a technical perspective.

...and any talk of Apple is espcially welcome here on sciforums, given that I am a died-in-the-wool Mac user :) (and now programmer)

At some point in the future there will be a dedicated General Computing forum.
