Thanks. I don't know if you can answer this, nevertheless, here it is: how does the reading experience compare to the iPad mini? While I am loathed to buy any Apple products - primarily because of my ecosystem choices - to gain a better reading experience, I may have to....though it would be a damn expensive reading device.
Depends on what exact device you would be comparing. I have a Galaxy Tab Plus P6200 running on stock Jellybean ROM by Samsung. For starters, its quite a bit heavier than the iPad mini, a full 33g. Although of course this is an older (2 year old) model, and the more recent versions like the Tab 3 7inch is lighter than the iPad mini.
It does have a slightly crisper screen due to a higher pixel density (170ppi vs 160ppi). The PLS screen on my P6200 is also brighter and has increased viewing angles and better picture quality than the IPS screen on the iPad mini. I have no idea what type of LCD is on the Tab 3 though.
With those in mind, the answer would be, for my specific device, it would probably be the same. The iPad mini is wider and taller, making it more unweildy, but at the same time, my Tab is heavier. So we'll call it a tie in terms of handling. I have a better screen, but it's an inch smaller diagonally than the iPad mini's so again maybe we can call it a tie.
In terms of handling, the bigger bezels on my device lend it to better one handed handling while reading, as your palm covers less of the screen while allowing a secure grip. The thin bezels on the mini makes the grip less secure as you try to keep more of your hand away from the front of the device. So this gives the Tab a slight edge, although this is heavily dependent on one's reading habits, and it may not matter at all.
However, I'd say that the best reading device for this category (7-8inchers) would be the new Nexus 7. The high res screen would simply blow you away, and the letters would be so crisp that reading would be a joy.
