Hello,
I'm looking for an ebook reader mostly for Manga. (I plan to use it for normal books too, but I would only buy it if I can also use it for Manga)

So from my limited research, the Aura HD seems the best choice for the larger and higher resolution screen. And for the extra SD card over any Kindle too.

My questions:
1) is the Aura HD the best choice for me? any better devices for my usage?
2) can I just rename my zip/rar files to cbz/cbr and use them without any other operation? (no resizing, optimization, etc). I never owned an ebook reader before, but I read of such operations needed for other devices to read manga properly (and honestly I don't think I'd be willingly to do it).

Thanks in advance!
