NP, also from Michigan - I went to school in Lansing for a while. Okemos to East Lansing is not something *I'd* want to bike. Um, no one's mentioned that it SNOWS there, sometimes 6 months a year. And not the kind of snow we get here where it melts a day or two later - it sits on the ground for months. Not sure I could bike through that, particularly not as a planned commute.
On the upside, Michigan has these things called snowplows. We tend to be unfamiliar with them here. So even if it snows 6 months of the year, the roads are generally cleared within an hour or so after it stops snowing. In 13 years of school in Grand Rapids (K to 12), I can count on one hand the number of snow days we had. The road crews are that good.
Housing prices there make me weep. My townhouse in Woodbridge cost four times what my sister's single family home in Grand Rapids did.
Also, echoing the recommendations to move to East Lansing, Okemos (even without being able to bike) or DeWitt rather than Lansing. If you're close to the University, East Lansing would be walkable. Just be sure you know if the house next door is an unofficial frat house before you move in!
And for vacation - Lake Michigan beaches rock! I fly home to vacation there once a year, I still like it better than any other beach I've vacationed at. Probably has something to do with the FRESH water - no salt!
