Comparing Apples & Oranges: confusing dual core PC reviews

[ahhaa]

zd/cnet sends me a bunch of emails on a daily basis, today this review of the dual core HP Pavilion Slimline s7600e showed up, with direct comparison to the Apple Mac Mini Core Duo:

The prices aren't similar, the CPU speeds aren't similar, the RAM & HD aren't similar, the cases aren't similar. Both units look like they'd overheat without half trying...

With Vista on the horizon (tho new delays are predicted) what are the real criterion that a dual core (big box level) buyer should consider?

Here's the MiniMac review:

A good home built PC with a slim and small HPC case most likely can do better than all the models in the review. Sad....
