Someone emailed me asking how easy/hard it is to use the Kobo one handed, especially if you're left handed (as the control pad is on the right).
It's a lot easier than you'd think. I did not use my right hand to hold the Kobo when making this video (it was holding my camera). When the Kobo leaves the screen I'm adjusting my grip and using my leg to hold it in place (which you'd have to do if you're using it one handed anyway).
And yes, I say 'scan' when I mean 'scroll'. I did this video in a hurry.
I do imagine your hand will get sore/cramped holding the kobo one handed for a long period. Because you have to turn the page using the button on the bottom right, there's little variance in terms of hand positioning.
