And this is compared to how many for windows?
At least Apple doesn't let them sit for 6 months or more.
So sorry to say, while nothing is 100%, M$ has ticked enough people off and made enough enemies out there that if it says M$ on it it's going to be a target.
But hey, that's OK.
The question I ask myself is this. Whom do I trust with my data environment? Can I trust M$? Absolutely not. Not any further than I could throw a cow down a country road. Their track record speaks for itself, and I can't trust their product to work.
Do I trust Apple? Much more than William Gates, you bet I do. Of course, with experience on all major platforms out there it's much easier to make an informed decision.
One I don't regret for a microsecond.
