Just read Engadgets full review of the nexus 10, generally sounds good, but light bleed is my one bug bare, and yes its there, and they confirmed it on a second device aswell!
Calm down slick. Even two devices doesn't mean that every product off the line will have it. Unless they had checked 20 devices and every one had the same problem, I'm not writing of the device. There are defects. Some people have Nexus 7's with no light bleed, others have it with some light bleed.
Light bleed is kind of a big deal to me too. I don't care about anything being really much over 1920x1080 (although it has to be at least 300PPI for me with Pentile displays, I can still see it), but light bleed might be the deal breaker here when I see this thing. It is not like I absolutely need a tablet with a good desktop, laptop, and phone. I'd be getting it for media and browsing around the house and workplace where screen quality will be the #1 focus.
