Don't let them scare you. Buy some real winter tires, put some weight in the back and drive away....
There are some other threads about this topic.
I drove every day this winter, with no problems.
The only real gotcha is that you have to buy at least two extra 18" wheels for the rear, because no one makes 19" snow tires.
The Winter/Summer switch does not seem to make much difference.
Go buy your Crossfire!
