Why isn't that set on as a standard?

Problem with Firefox I find is that you need the add-ons and those plug-ins to really make something from it Opera is a better one package solution but isn't so customizable as Firefox.

Indeed IE8 is certainly better then the previous version but still it has some problems with some codes. For example here on the forum it has problems whit the image resizing codes

It's only 10mb that a browser so no worries about that and most likely your surfing on the web will be faster and snappier.

Well I do have a slight problem with the X-ray type though since even a slight doses does some damage it does not have to be harmful in anyway but still the less the better.
However the millimeter wave scanner seems to be perfect for everyday use it's hard to find any arguments about health risk against it, privacy is still a issue with both but it seems like an improvement over the currently used system, better safety and privacy.

Of course you can manage without one, I think you will find it not worth taking a meter with you and using it all the time, it's just faster and easier to use the camera meter.

If you want to get a good exposure just get yourself a greycard, if you take a metering from that with your camera then you're set.
If you use the grey card use the camera in manual Manual mode with the green button you take a metering and when you use the exposure-lock it locks the exposure but you can still change your shutterspeed or aperture and the camera changes the other one so that the exposure stays the same.

You can also use the cheap man grey card and that's the asphalt of the road, it isn't 100% the right grey but it gets you very close, at least close enough to have a good exposed first photo, then one or 2 clicks on one of the wheels to adjust shutterspeed or aperture and the exposure is most of the time perfect.

4 is fast enough for photos, certainly JPG, for RAW also since the camera has a buffer but you can get more photos continously with a faster card.
For video, at least for HD they to slow, SD... I believe it could handel that. So when you get a K7 you can only use video for 15 or 20 seconds or so since then the buffer is full.

As a side note Class is a minium constant rate rating, class 4 means 4MB/s and class 6, 6MB/s.
From test with the Extreme III they came out with a constant speed of 18MB/s so a class 18.
Sadly all isn't that simpel but it gives a fare idea that the "class" thing is a bit outdated

This is not 100% true more like 2%, the microwave lenght is broad and you need a specific wave length to excite/resonance a certain molucule.
Those in your microwave or designed for watermolucels those in the scanners resonate oxygone and are even stopped by water so they won't have the power to enter you since you consist for 70% out of water.
However they aren't 100% safe, they can tear apart DNA... it only takes a heavy dosis for continues of 6 hours though and how long takes a scan, 5 second maybe.

Also the wave length is use for comunication so you're already exposed to it if you want it or not.

They don't do that anymore, they "chip" pets now a days

First argument is not based on anything, probably making a phone call with your mobile is more harmfull and also there is the millimeter wave scanner, it's almost the same but it use differnt matter for exposure. You can see the extremely high frequency that it use as light really, it's the same and it's natural, only the dosis is higer so it's like taking a photo with a flash, very comparable with infrared photography for example.

Invasion of personal space... I don't get, how is it different from being searched?
It's even better since the person searching you doesn't even see your face or thouch you in any way.

I would say you don't really need one with digital, you can see your exposure right away and adjust as you see fit and even use the histogram for advice.
Of course a light meter have some merits but they aren't big enough to get one for most photographers.

Yes most of the time but IE is known not to use the standards well so web builders often need to use tricks to get a site to work right on IE.
Safari and Opera have the best support for standards and also Firefox and Google Chrome work with all the current ones but might have some problems with the very new codes but you don't see those yet and by the time you see them more the support would be there.

Really though, you would do web builders a favor by not using IE
