Recently I walked in a store that had a bunch of apple machines in a corner. ( mostly imacs ) and pc's . I couldn't stay and look at the apples, which I always do . :-) I didn't have the problem looking at pc's. I think that is because in "idle" mode they throttle back to low speeds. But I admit I have the same problem with cell phones, bluetooth and wifi. But at least those you can switch off. ( When I am in a hotel, I even allow myself to use wifi. ) There is enough research that shows that these frequencies are dangerous, but I didn't want to start that discussion. I actually had this discussion with friends that are RF specialists, and they agree with me. They are just doing there jobs :-) .

I get a horrible headache. So I have to switch it off. The most common causes of this type of problem are: - visual - different screens do different things to different people. A good ophthalmic optician (not just someone who tests eyesight, but a professional eye specialist) will be able to advise and may well be able to suggest solutions I am very sure its not a screen problem. - auditory - some computers emit high frequency noise that can give some users headaches. An easy test is to wear closed headphones - stress. same for above. There are also many causes of headache that can be triggered by computer use. A neurologist will be able to work through those possibilities. weak ? To the best of my knowledge, no-one has ever shown that such low levels of non-ionising radiation have ever generated this sort of effect. I am not saying that I do not believe you, just that if it is true, I think that you will be unique, so of enormous interest to doctors. I am not unique, do some research. Although headaches are very common, recurrent or persistent headaches can be medically important and you should see your doctor if you suffer from them.
