according to the most important thing is SAFTY...
we all love reading in our bed and the eink display is so fragile that u cant even imagine. a small press on the screen n d screen crumbles( very possible when reading in bed)
pp come wit fortified cover n i think even accidently sitting on it wont do any harm. sony's cover is exposed to it. sony people r really shrewd they dont even provide a charger and working with reader lib is pathetic. u cant replace sony' battery ursellf its so complicated(again u cant imagine how much) i crcaked d screen while replacing.
so buy pp as it ll last long
i ve experienced that a 5 inch is better size than 6 inch it becomes bulky.
if one wanna ve 2 reader then i suggest
1)size 5 n
2)size 8 or 10
