I was uneasy about its size, moving from Aura HD - sometimes over my time with Aura HD I found it bit unwieldy. As it stands right now, Aura One is at the border of "still can fit into a pocket of my jacket". I'm still getting used to it; I can hold it comfortably with a single hand, but flipping pages without using second hand is a bit of a challenge. Not impossible, and not that inconvenient, just a bit tricky (move thumb up, tap the screen).
Everything will probably change once I get a cover and the overall contraption gets even heavier...
