I love the device itself (first a Touch, that I gifted to my mother, now a Glo) : lighter, faster to read, always something to read versus paperbooks, able to read at night or in poor light. Charges withe the same wire that my phone.
I love the firmware (despite bugs) : epub's main format so I'm not tied to a bookstore, works hands in hands with Calibre (that is a most convenient software, cheers for the developpers), low battery consumption. Ability to set the font size to the one I'm comfortable with, build-in dictionnaries (even if they are poor, not much is better than nothing). Shelves management (even if it could still be improved).
I love the will of the Kobo team to hear the consumers and try to improve our reading experience :-)
I'm happy with my Glo, I don't search anywhere else as it globally suits my needs
