Inside CNET Labs: Windows virtual machine performance on the Mac examines how well Apple Boot Camp (i.e. "running Windows"), VMWare Fusion 1.0, Parallels Desktop 3.0, and CrossOver Office compare against running Microsoft Windows. Oh, and they also throw in a performance comparison of the same software running on Mac OS X, if it can.
Performance comparisons are important, even if this one is perhaps a little frivolous — and explained in a somewhat silly fashion. I feel like I'd be more likely to trust a different source, such as Ars Technica or XLR8YourMac.com or BareFeats.com after reading this article, despite its utility.
This is partly because I wonder what they really tested. One question I have for CNET's "Crave: The gadget blog" people: how did they get an eight-core 2.66 GHz Mac Pro? Last I checked, Apple only sells the eight-core model in a 3.0 GHz version. The 2.0, 2.66, and lower-end 3.0 GHz systems all have a maximum of four cores (all using dual-core Xeon CPUs).
Update: Curtis, ever-vigilant (but without a URL known to me, so he gets no link), points out via IM that CNET apparently
[Bad link]. We call them jerks. What do you say?
