Can anybody provide user feedback on the new kindle and nook ereaders that use e-ink and are backlit? The kindle is the pagewhite I think and the nook has the glowlight... I'm just looking for a more comfortable alternative to my prime for night reading...and also a device I'll be less fussy about when I'm on the beach or camping...

My main concern is being able to sideload my own epubs and the amount of space available...any help's appreciated.

Cheers!
