Damn, at 10mm thickness that's a chubby little SOB, nearly twice as fat as my leaf 2. And with a tiny 4.26" screen on top of that, yikes...I love my 7" screen, I'd hate to read on a screen smaller than that.

Still smaller than a novel and too thin and you can get hand cramps.

I've found the 6mm thickness is perfect for my hands, granted I have a medium-sized male hand and not a huge grappler. 10mm thickness is a little too thick IMO for a nice feeling, but not a deal breaker. The very small screen is a definite deal breaker for me though.

That's what she said

If course she did, no one likes reading on a small screen, it's terrible.
