I know mocking windows is a fun past time for many, but lets look at a few facts we already know:
1. The machine is terribly out of date, without even SP1
2. I dont know of any os that is safe to use out of date
3. Windows is targetted more because its used more

And 3 is the kicker. Not being able to use windows with bitcoin is eliminating what, 80% of the world from bitcoin? Sounds like a great plan.

Besides, many of these types of attacks could probably have been prevented with an encrypted wallet, currently a HIGH priority of devs, and yet nobody dares blame them. And to those that say 'encrypting the wallet will make no difference' do you really think that the devs are thus adding it to pander to 'noobs', but that is secretly known as a waste of time?
