Hmm my SP8000's handled Chicago's winter really well..
I drive very gently in the winter, but i do get drive fast (in max speed) on highways and the like.
I had a blast after a heavy snowfall and my girlfriend forced me to a mall at like 9:00am on a Saturday, i had a whole unplowed parking lot to play in, and man did i play, throwing my car around, powering through the drifts, it was beyond fun!
Also the SP8000's handle rain VERY well. I was in an absolute torrential downpour in Pittsburgh this past summer, cars were pulling over and sitting it out, but i was more than fine, never hydroplaned or anything, car was incredibly surefooted.
Makes me think that i can go with a high performance all season tire and be happy with that. Not disputing the others here, just my observations. Im not someone who will keep a winter set of tires/rims (at least not at this stage in my life) that is what Quattro is for, IMHO. Of course you tone down your driving, but i still drive 8/10th's what i do in summer in winter.
Cheers
I can see where the dunlops would be fun in an empty parking lot, but that's exactly what a snow tire is designed to avoid (among other things...rocks, trees, other cars, curbs, ditches, etc.).
Here's a bad analogy...when it snows, do you walk around outside with your dress shoes on? It would probably help a lot if someone gave you a pair of crutches (quattro) to help you along, but in the end, boots are a better bet.
If you're happy with them, that's great...as you pointed out, you can get by with them, provided you drive VERY carefully, however for those opposed to white knuckled commutes, snow tires give you as much confidence in snow and ice as Sameer noted in the rain.
