I'll second the recommendation for the Hakka Q's as snow tires. I live in an apartment, too, but there's enough room in the storage locker for a set of tires and wheels, so, in the winter, the Borbet alloys and "summer" tires come off and the Hakkas (on original steel wheels) go on.
Like some of the other posters, I live in metropolitan Minnesota. I find that I rarely have to drive through more than a few inches of unplowed snow. The big problem, though, is that the plows and salt level out the slush and I'm frequently driving on packed snow and ice. The Hakkas stick like glue. The NRWs, though, might be a close second for someone who drives on largely-cleared roads.
