Ok, this is going the usual way boards are going. If you are here posting, first read all the post history.
This is really an old topic going back tens of years.
1. First of all, the discomfort is not unexplained. Potential sources of the discomfort are well known and coutless people have identified the problem to be something else than RF radiation.
2. I have never said that there are no RF sufferers. I may be one. I got a very slight headache from a cheap wi-fi transmitter approximately 6-7 years ago. The headache was only slight and may have been due to the almost inaudible high frequency pitch emitted by the transmitter. I changed all the devices to be wired and had it that way for several years just to be sure. I now use bluetooth and wifi without a problem as I have identified problems specific to me (related to this case).
3a. By an agenda I mean generally what drbaltar said. I have an agenda of helping people as objectively as possible. I have helped many people to identify the problem correctly related to this type of discomfort as I am myself a serious sufferer.
3b. By agenda and scaremongering I refer to the few unlucky people with a serious issue and who are so fixated with their issue that they scroll through all possible forums for help and understanding. In the mean time they participate in each of the forums convinced that all the symptoms others are describing fit his or her diagnosis. This may be trying to help, but I feel it's highly subjective and will only spark considerable clashes of viewpoints.
4. I see articles posted here refered to as scientific evidence of some sort. But they are of bad quality and cherry picked and I don't like people misusing scientific research to prove any point. There are also countless studies where there has been proved to be no linkage between RF radiation and people who claim to be sensitive to it. The reason may be that for most it is psychosomatic, or the discomfort is of different origin. I do not doubt that there are those who actually suffer from RF/EF sensitivy, but the number of those truly suffering from it are trumped by the sheer volume of people who think they have it due to misdiagnosis or due to psycosomatics (placebo effect). There are also plenty of cases that prove correlation, but the evidence is hardly conclusive due to the poor specification of subject groups.
5. Please read my earlier posts to actually know what we have been talking about:

If my memory serves me correct, the thread starter has already notified that the case is closed (the problem identified). So this is not an ongoing debate as such.
6. My personal experience is that I see the display flicker, and I have connected that with my problems. This is very tangible evidence, but from what I've understood, most people do not see the flicker. With some devices the screen flickers more, with some less. The ones that flicker more cause me almost instant nausea.
I have written most of the topics here with a samsung galaxy note on 3g and on wifi alternatively, often using bluetooth keyboard much of the time - I have not had one dizzy spell or a single headache using this combination. Galaxy note is not however the least flicker phones, but it's better than most. I preferred perhaps my previous phone, ZTE Skate, for flicker. However, brand is no way to tell whether the phone/tablet/laptop is good for you as it is entirely dependend on where the screen (&backlight) has been sourced from. One of the lowest flicker laptops has been Dell, and incidentally one of the highest also a Dell.
7. Just to make it clear, this is not an attack on Apple or iPads. I think the ipad infrastructure is superior to that of android at the moment. Sadly more power efficient screens (higher quality?) also seem to flicker more, and thus are more likely to cause the discomfort. As all ipads appear to flicker, it seems you have no option but not to use your ipad if you value your health. Pixel density / resolution has nothing to do with the nausea apart from a little pixel grid irritation which would make previous gen worse, not vice versa. EF/RF is a potential source, but coincidence rate is likely to be one tenth or less in comparison to the perceived nausea from flicker.
In short, if you have never suffered before from nausea eg. when using a laptop on wireless, but you do when using and ipad, it is likely that it is due to the backlight flicker. I know that constant and aggreting RF/EF exposure makes sense, but the change in display technology is a more obvious culprit, and easy to test and solve (eg. my case).
I think this thread should be closed as now there appear to be only trollers or people who have not read the entire thread. LCD backlight and RF discomfort are well documented in other places too should you want to continue the debate.
