I’m sure published exploits will increase but not to the levels XP experienced. The unix security model alone makes a huge difference.
Actually Windows runs really well on the Mac hardware primarily because of the driver disc that Boot Camp generates. An OS is only as good as its drivers so it can best make use of the hardware it’s running on. Plus, if you priced out a similarly spec’d Dell or HP computer I think the prices are pretty close. Building our own rig is obviously cheaper than both.
And people need to realize this and stop :deadhorse:
That said, if you want an uber secure OS install OpenBSD. 2 exploits in 10 years.
