Something that you may want to consider. If you build a steel framed home, then you buy a big screen TV and want to hang it on the wall. But the thing is huge, and you need to "mount it on studs". I'm not sure you'll be able to do that, or at least, not easily with a steel frame. Maybe there is an alternative, but a buddy lived in a high rise apt and couldn't wall mount his TV because they didn't have any wooden studs that he could mount to. I would assume that other things may pop up from time to time that were similar.
