biGPlant, I'm also looking for a reader for similar purposes...manga, comics, pdf and maybe fiction.
I have a couple of tablets (Android and iPad) and a Kobo Forma (8" screen). The Forma is wonderful for fiction and not much else.
The new, colour readers from Kobo have piqued my interest, mainly for reading comics, but they just aren't big enough. I want a 10" screen reader, with colour and decent pdf capabilities. I'd imagine we'll see a 10" colour reader at some point if the Kobo devices sell well for them, but I doubt the pdf handling will improve much.
So, at least for the foreseeable future, I'm sticking with a 'normal' tablet.
The iPad is fantastic for speed, build quality, battery life and the screen is great. However, the iOS experience is beyond dreadful. I cannot get on with being forced to work the Apple way and having no access to the OS or directory structure.
The Android tablets can be just as good as the iPad, depending on the brand. However, Google still hasn't adapted Android to deal with tablet sized screens in the way Apple did. It makes for some frustrating experiences with certain apps. That said, as things stand now, my only real go to for anything other than fiction is a 10" Android tablet.
I live in hope there will be one device that fits all, eventually
