Agreed. I don't know how much, since e.g. attacking a Flash bug might work for most of them, but then again trying to force your malware to load at boot might be different from one distribution to another... which means more effort even if you do.
Also, Microsoft just makes some really stupid decisions sometimes, such that the operating system should automatically execute arbitrary code when you insert a CD or USB disk. (I think this behavior may have been finally removed in Windows 7?)
Autorun/autoplay does still exist, but the system prompts you about what to do now. A bunch of people were infected by some worms despite this because someone managed to make an "unsafe" option (run the program) look too similar to a "safe" option (view the files on the USB drive in Explorer). A patch removed that possibility for confusion.
I do think that Microsoft is a specific target though, but more for their history of shameful business practices. In other words, if you use software from a company that people think is evil, you are at greater risk to be hacked yourself. I think this makes a corporate case for "Don't be evil."
This probably used to be true, but most malware authors these days don't do it to make any kind of point, they do it to steal data and make money.
