Question [Q] Can anyone recommend a 10-11.6" tablet for reading scanned pdfs?

Hello,

I currently have a viewsonic g tablet. Due to it's lower resolution, I still have to pinch and zoom when reading a scanned pdf since I can't reflow the text. For those who have retina screen tablets, is the tiny print of scanned pdfs more legible? Does more pixels translate to more clarity? I'm looking for either an android tablet or even a windows 8 one (Chinese tablets are welcomed) that's at least 10-12" and has a retina screen min 1080 or higher, at least 2gb of ram, and preferably something with good viewing angles and slots for external storage media.

Does anyone have any recommendations? I've been looking at the voyo a15 but I heard battery life was really bad at 5 hours or less.

Thanks
