Hi Lisa,

I also have a 27" iMac which I bought two years ago before I knew that I had EHS. iMacs are a poor choice for those with EHS because the CPU is inside the display. The electronics aren't well shielded, and you can't move far enough away. You can verify that there is plenty of radiation coming off the computer by using an AM radio. When I set my radio to 1.7 MHz it starts getting really loud at a distance of 1.3 meters.

When I found out that my iMac was making my headache worse, I made several changes that ended up helping a little bit, but it's not a long-term solution. I switched to wired keyboard and router, and set the computer as far back as the USB cable allows. I reduced the screen resolution and magnify the text as needed. Remember to turn bluetooth off in system preferences. I also use a grounding mat, but I'm not sure whether that helps.

I had heard that the MacBook Air might be a good choice since it has an LED display and a solid state drive, and you can run it off the battery. So I bought one a few months ago, and was shocked to see how strong it radiates, worse than my old MacBook from 2002! It's a little better with an external keyboard, but then the display is a little too far to see since it's only 13". So I'm planning on getting an external monitor and using the MacBook in clamshell mode. I'm also thinking about shielding the cables and the keyboard. A Mac Mini might have been a better choice...

Luckily, I don't seem to react much to my iPad, so I'm trying to use it as much as possible.

Hope that helps,
Rolf
