GENERAL OBSERVATION: Regarding views, I was in my apartment on the 16th floor of my building facing away from the skyline for a long time, and had been pining to move the skyline side of the building for ages. After 25 months in that unit, I hopped over to the 20th floor on the skyline side, and it has a very nice view of the city. After a month, I...don't really notice it anymore? It's cool having people over so they can be wowed the way I was the first few days, but it's pretty much just a desktop background at this point. The rent is ~$100/month more, which isn't that big of a deal, but I don't know that I'd, say, take out an extra $50,000 of mortgage to be on floor 30 vs. floor 15, or whatever.
My opposite experience - last time I was on the 24th floor with a view of downtown Indy, I spent more hours window-gazing than I can remember. I'd pay extra for a nicer view than I have now anytime.
