I think you underestimate the significance of the iPhone, in the grand scheme.
MacRumors = Apple News and Rumors. It's been true for 7 years. If you want MacBook or Mac Pro only news, you can visit:

I'm tired of making excuses. I know some people don't care about the iPhone, but 50% of people don't care about the MacBook, or the Mac Pro but that doesn't mean we are going to stop reporting on them. iPhone is a big part of what Apple's doing, and will be news for months/years to come. If you want a Mac-only news site, you can use those subsections... but you'll be hard pressed to find an Apple-related site that is not covering the iPhone.
I guarantee you we'll be sick of Leopard stories the weeks surrounding Leopard's release. This is how news works.
