Just for checking, i converted some pdf file to ePub with this link:
http://ebook.online-convert.com/
And it did solved my original problem but as you mention, i feel that the size of the device is too small for reading a pdf (even if it was converted to ePub) eBook on it.
So what is you're recomended for reading pdf eBook?
Should Kobo aura one which is 7.8" would do better?
I dont want an ipad couse it doesn't have the Eink screen.
