I like reading, so I buy eink readers, the Sony PRS-500, the Kindle Keyboard, Paperwhite 2+3. I rarely use it, always put books on there to read and never do, but I still read on my laptop, I recently wondered why, I am trying a cheap 6in 1080 IPS phablet with popsocket and seem to read more on it. Is it that I prefer reading on LCDs? I thought that eink was better but I really don't read on it at all compared to an LCD. I have a jail broken PW3, a buttonless slow device it just plain sucks for reading IMO. With awful PDF support, it's expensive and cumbersome, only goes by pages (rather than being able to scroll comfortably), the software is really bad because it is proprietary or koreader. Having a white font on black screen is supposed to be a premium feature for instance. So strange that the device is somehow too small for me, but a smaller LCD isn't?
The Chinese eink are way more expensive than I am willing to have what a monochrome screen could do with good refresh instead of the tradeoff of slow refresh for $$$.

Right now I am wondering if its the PPI, slow refresh, bad software, or perhaps the size (in the case of PDFs). Has anyone had good experiences with OLED displays for reading or seem to prefer to read on LCD screens?
