Yep, true that it was so but things changed over the time.
In the past there are too many Windows users which attracted to the hackers, obviously... not only that but Windows with IE (pre-IE 8) was so exposed "like a back door without a lock" which it made easier for them to crack.
Now IE 8 and 9 are both open browsers which sufficiently improved its security unlike before.
Also there are more and more MAC users that attracts hackers, likewise. I think the Safari is the problem just like the older IE versions for the Windows were. They also knew that many MAC users still think they're as safe as before but ain't so anymore. There are several articles popping up about it as of late... how interesting the times changes since then!
