There's nothing new on that link that contradicts what's been said elsewhere on the thread. Macs are insecure, but there's no market for the malware. It's simple security through obscurity. Mac lacks much of the layered protection now built into Vista/Windows 7 which shouldn't be the case as it's built on BSD.
The case still stands though, it took hours to crack Windows compared to Macs, this shows how much more secure the standard Windows installation is, also M$ responded within 24 hours of the security issue. Whilst that doesn't seem important, remember they was holding a exhibition and launching IE 8.
Apple really needs to step up to the plate and deal with security now rather than do a Microsoft and ignore it till it became a issue. This is what happened to XP and was one of the reasons Vista took so long to come. Microsoft learned the hard way and needed to re-prioritise it's security model.
