Kindle/Nook Question?

Thinking about getting an e-reader. I don't give a crap about the pedigree, so I dot care if its a kindle or a nook or whatever else, I just want to be able to read in the sun, so first of all I don't want to hear about the freakin kindle fire. You can't use those in the sun and from what I understand the screen covers are useless. Dont be a smart-alek and tell me to sit in the shade, that's not what im looking for. If you say something like 'get the fire' or 'just buy an out-door umbrella for shade' I will report you for not reading the question. I'm sorry but I'm sick and tired of getting that wherever I look. Okay, now that that's out of the way here's the question.

I'm sort of an Americanized-otaku, so I like manga, and there aren't a whole lot of them on the book stores available, and even less regular books that have been translated. I know that, I've done my research on that bit. I want to know if there are any that you can use in DIRECT SUNLIGHT that can either 1) use a web browser or 2) have image files transferred to it. Thanks for reading the whole question and hopefully for your help.
