If I'm going someplace unfamiliar, though, having a navigation aid is pretty useful. I find that the voice directions from my phone mostly work.
(I was just going to say, "I use BSD, you insensitive clod.")
My apartment is 640 square feet, and around here that's pretty spacious for one person. 850 square feet would be quite big. Why do you need so much space? Do you have a multi-person family, lots of pets, or is it just that you've become accustomed to spreading everything out?
I'm not the only one who feels this way, either -- there wouldn't be such high demand for apartments in places like Manhattan (where many apartments are much smaller) if people weren't happy living in such spaces. There are a lot of benefits to density -- things like arts and culture and the ability to walk places without jumping in a car -- as well as advantages to smaller living spaces (lower heating/cooling bills, not having lots of space to fill up with junk that you'll have to deal with when you get old, etc.).
