Just to add a few more points:

Look into the controversy surrounding high-voltage transmission lines. Same EMF arguments there, but they've been around longer so it is easier to read up on.

It reminds me of the question surrounding B9 (folic acid). So they found that people who took folic acid were less likely to develop colon cancer. Great! So the researchers ask patients who were in remission to take extra folic acid. Guess what happened? The cancer came back with a vengeance. Turns out, the same mechanism which helped block the cancers from originally developing, makes the cancer go like gang busters once established.

Is EMF harmful? We don't know. Is avoiding EMF helpful? We don't know. In my opinion, the reasonable approach is to treat it like a coal mine and let the early adopters be your canary. If they start dropping, get the heck out, but don't worry about it until then.
