Apple, Linux and Firefox Unstable?

Story Text:
The New Scientist reports on an interesting but totally inconclusive report that M$ products may be as secure as non M$ products

Until now, the open-source Firefox web browser, Linux-based web servers and the Apple Mac operating system OSX were heralded as more robust to hacker intrusions and viruses than Microsoft's Internet Explorer and the Windows operating systems.
So it came as a surprise to the security community when all three came under attack in two security reports, funded by Symantec - the California-based anti-virus software vendor - and Microsoft.

Despite the rather dodgy sources I do agree the points they're raising - M$ is certainly flawed but Linux and Apple are really not perfect and as they get more popular they're going to be targetted more.

Cluley argues that this is irrelevant because hackers are still not interested in attacking Linux systems, partly because there are far fewer Linux users, and partly because the users Linux attracts tend to be more tech-savvy and so more likely to patch their own systems.
But he says that this could change in future. "There are a growing number of users for these alternative operating systems so we shouldn't be complacent," he says.
