You do not need disks. I commute 4-5 days per week, in Alaska where you can be assured of 6-months of real snow, without disks, with no problem. The two bikes I have with disks actually are more of a problem (cable actuated) due to icing of the cable mechanism.
I must note that the previous post about rim-grit may be a concern. I'm going through rims about every 3000 miles or so due to wear.
