I am not a big fan of Microsoft either, but lets face it, when they had 80+% of the market they had 95% of the hackers looking to exploit them. Now that people have a decent choice and more and more of us switch then these other companies are finding out what its like to have thousands of people hacking their code instead of a dozen. People start seriously hacking hard enough and they will find close to as many vulnerabilities in Mac and FF, just watch the number of patches keep rising.
What do you base this bit of wisdom on, pray tell?
Sounds like the old "nobody wants to hack it because there's only 20 million (or whatever) machines out there" argument.
Which makes me wonder why there are viruses for freakin' CELL PHONES with 100k units out there?
