I have the original Kobo Aura (flush capacitative screen). I'm totally happy with it, though I'd try and find a Kobo Glo HD if it broke, just for the added resolution (I have some comic PDF's that could do with some extra resolution).
I used the original Glo before the Aura, and I loved it just as much (and the Touch before that - no complaints except that they're a bit... fragile

all of them).
