Is the PowerMac the odd man out?

Apple likes simplicity, and they excel at making complicated computer and hardware purchasing choices simple for their customers. Apparently, 'simple' means that the PowerMac gets no love from the rest of the Mac family.

This is a snapshot of the top of Apple's general Mac product pages. I was browsing for some details on my iMac G5 when I noticed something odd about this lineup: the PowerMac isn't sitting alongside its brethren. While it kind of makes sense, since the PowerMac is aimed for a slightly different audience, I still think it should at least be obvious and available in that particular navigation (I know it's easy to get to from other main links) since one never knows – the leap from an iMac G5 to a work-horse PowerMac might not be that tough to make for more customers these days.

Am I over-reacting here? Or is someone already proof-reading a site alteration petition for Apple?
