I didn't buy "snow" tires, I bought "winter" tires. I don't care if there's snow or not, or if you've been driving 24/7 for the last 50 years. The tires are made different for a reason. If you're not interested in the decreased stopping distance and better handling in the cold/snow, then stick with all seasons. But, I would never recommend it.
IMO, I'm never okay with the phrase "good enough" when it comes to tires on the car I've wanted for a decade. We'll all seen that soccer mom take a corner wayyyy too fast in her surburban in the snow. Am I confident with my ability to drive properly with all-seasons? yes. But, I'd like to do anything I can to avoid other drivers.
