I got a Sony Pocket and a Galaxy Note and I strongly prefer the Samsung; granted, in full sunlight with th light on the screen the Sony is better, but in all other situations I prefer the Note; very pleasant reading (btw, AMOLED is not a backlight technology), with a reader like Mantano that lets me customize the colors, fonts, gestures etc. etc.
Got profiles for sun, normal, and night and with one swipe I can adjust the screen intensity further.
And it makes sweet music, is a good GPS, nice for a break with Freecell, Whatsapp, SMS, there is even a phone in it somewhere. Battery life is decent, more then enough for a transatlantic flight reading and listening to music, and it is much compacter then the Sony, while the screen is roughly the same size.
At home I prefer reading from the Ipad; nice large screen, with Bluefire reader I made a very friendly to the eyes perkament background, again, one swipe gives the right amount of light.
I do not find e-ink devices are more easily readable and give less eyestrain, and I'm 54.
So IMO I prefer tablets/big smartphones above dedicated readers, equally readable, much more versatile.
