Is it just me or does it look like severe light bleeding isn't inherent to the technology.

Most of the answers I'm finding in regards to light bleed say it's caused by an improper seal between the lcd screen and the bezel/front panel. (which seems to coincide with the glue (which is now what holds the front glass on) isn't being attached properly, isn't dry, etc)

I'm sure backlight bleeding is not a standard feature. Sounds like bad quality control. Though I don't know if it would worth it to Apple to find a dark room to test each unit after making them. They'd rather deal with the small number of picky people who come in complaining about it.

Amazing how bad some of the pictures I've seen are. But it seems like this is something a "non tech savy" owner simply overlooks. IMHO (flame away, but know I bleed aluminium ) this is up there with antenna gate, but most people are just clueless.

It's just a non issue for me with my unit. I don't see it in normal use, and I'll never be turning up the brightness and using it in a totally dark room (or using it in a totally dark room period). I don't care that there's some light bleeding in those situations as it doesn't affect my use of the iPad 2.

On top of that, I do very little consuming of dark content like videos as I hate watching movies on that small of a screen and generally just wait until I can watch things on my 50" TV. I mostly use it for reading newspapers and pdfs, surfing the net etc. which doesn't get noticeable bleeding even in a dark room.

I get that some just want a 100% flawless device for their money. Myself I only care that it's flawless for my uses. I don't see the bleeding when using the device normally, so I see no reason to care about myself. Everyone has to make their own decisions though as it their money and their device.

I think most people feel that way. The people who have to have a perfect device for the sake of it, seem to me, to be few. However there are a good amount of people who like you think it should be flawless (or as close to as possible) for their uses. Their uses just happen to include dark screens.

I always turn my brightness on my iphone down all the way at night in a dark room otherwise it's too bright. However I've seen some people's ipads where it's visible in normal lighting too which to me would be worth having replaced.

I don't think anyone can deny there have been higher than average amounts of quality problems ranging from bleeding screens and panels not adhered properly, to chips/gouges.

IMHO, I think quality control probably is not at the top of the list for Apple at this moment in time. I mean it is simple logic. Apple is simply struggling to make more than the demand for the iPad 2.....

Ya, I wouldn't say it's not at the top of the list because they don't care, but because it's the only way to get enough ipad's made. If you make 10 ipads and 2 are perfect, 5 are ok, and 2 are bad and 1 is horrible, you gotta make a decision on where to draw the line on what ships and what doesn't. I'm sure traditionally if it was up to them they'd only ship the perfect ones, but when they're sold out across the country I'm betting they're shipping all but the absolute worst.
