Well in all fairness, Vista will basically be a copy of OSX Tiger which has been out a while. Meanwhile Apple is moving to Leopard next Spring, about the same time as Vista is released.
that's the bottom line, Apple always seems to be one step ahead.
XP? Had a plethora of viruses. Even with Nortoin and Zone Alarm pro they still got through. No need to buy any anti-virus/anti-spyware software now.
The Mac just works and is super fast, it's a big difference to be honest.
nothing wrong with MS when it works of course.
