Actually I'm REALLY GLAD that linux owns such a tiny share of the desktop PC market. This means that evil virus hackers have almost ZERO incentive to invest their time crafting attacks on linux desktops.

I'd say you've got it backwards - the high value targets are the servers more so than the desktops.

We used to worry a lot about someone getting into a salesperson's laptop, and using that to get to our backbone.  We created a windows-only network for them, with mandatory access control and physical separation. 

 At least one closely-regulated customer wouldn't let anything intel, much less PC, onto their back end networks Only a colleague and I who had SPARC laptops had direct access to the data center from the outside. Everyone else had to log in to a gateway box and work from the command-line.  (For some reason they didn't have Macs)

The underlying problem is called "transitive trust", where the attacker works through layer after layer because they each trust him a bit too much. And the first step is always a salesperson's laptop (:-))
