Aura H2O much better than Glo for PDF reading?
 

I'm close to buy an Aura h20 since I got some PDF that are hard to read on my Glo (big PDF page: the text still too small and a bit blurry, even after applying little zoom to hide margins)

I know the screen of h20 is a bit bigger and has higher definition, but is there a real difference/benefit between glo and h20? Or should I wait for bigger screen device, like 9 or 10" ?

Depends on the type of PDF you want to read.

I have read PDFs in both Kobo Glo (not the HD) and H2O.

Firstly, piece of advice - Use koreader to read pdfs, the reformating is great.

For literary books and scientific papers both are fine, however if you're into heavier content (like presentations in pdf, or college books) the extra screen space really makes a huge difference, and I would recomend the H2O, which can do these reads. On the Glo they are somewhat impractical.

For reading pdf formate books sometimes really need larger screen. Sony sells 13.3 inch eink device.. Onyx is developing similar product with Android OS. Both devices have mobile read threads.

A tablet is better for PDF and a lot cheaper than these 13.3" eInk devices.
