Just to clear up any confusion here - you could get a virus on any internet connected device!
Previously when >90% of systems were running MS Windows, it made sense that virus/malware writers would create malicious code targeting them.
Microsoft are still the main players, particularly in corporate environments, but now that Apple (and Google) are gaining a far greater share of the market I wouldn't rule out viruses being written which specifically target them...
Bottom line, if you're browsing the net then it's good practice to protect yourself!
