For me, the decision about whether to get winter tires comes down to a couple of things. Of course, if you get a lot of snow or the roads aren't well salted and plowed around you, it's a no brainer. For the rest, it comes down to how cold it is in winter (and/or how long your winter is) and whether you actually want the superior traction of summer tires the rest of the year. Winter tires are not just for snow, but they have a compound that is designed to remain softer (and therefore grippier) in freezing temperatures. All-season tires are a compromise in both winter and summer, but they will probably be fine if you don't drive the car too hard. If it doesn't get too cold where you are and you don't feel the need for a summer tire, you can probably get away with running all-seasons year round and avoid having to swap them. But if you are going to have a summer tire anyway most of the year, why not have a dedicated winter tire? You get better performance and peace of mind when it snows, and it will probably still be fine if it gets a bit warmer for a day or two. It's also worth noting that winter tires vary in terms of their focus on snow vs. ice vs. clear road handling. I have the Michelin X-Ice's and I found their snow/ice handling to be solid, but I particularly enjoy the fact that they are very quiet and comfortable on the potholed winter roads around here (going to 15in wheels helps a lot too). Hope this helps.
