Terry has 2 Kindles...one of which is one of the biggies [with an absurdly small keyboard....lousy for poor eyesight]... probably generation one and 2.... and the Oasis is something like 8th generation.
She's gonna wait a few more generations...as features need to get trickier to justify the change.
Curiously, her eyesight is such that she uses the largest font available...or maybe a few dozen words per 'page-turn' which means they need to be recharged every night....not days/weeks like 'normal people'...
