It's not as bad as all that, of course. But there are a variety of changes. It's often more a sense of the lack of urbanization/development around you than it is actual stuff. Though--depending on what you'll have--there are things like making sure the well doesn't freeze up when it's cold, or dealing with a septic system, or knowing that you could be without electricity for days, not just minutes or an hour or so.
Ithaca's a really nice place. I went to school there for a few years, though that was a long time ago. Recognize that the spring and summer are particularly nice, but the winters can be brutal.
If there's a way, try country living for a while. See if it's what you really want. Maybe rent a place up there for a while.
Also, obviously, talk to some Realtors who are active in the Ithaca area. I'd expect a number of them have helped people like you make a decision on whether a more rural environment would work for them.
Hope that helps.
