Aura HD Got two questions

Hello!

I got a Kobo Touch since two years now and I would like to be able to read at night outside. I don't like to read on a tablet so I'm looking for the Aura right now.

1- Is the back that slippery?
2- Can you hold it with your left hand?

I like the rubber back of the Kobo Touch and I'm afraid to miss it.

I look everywhere but it seems not in stock anywhere, so I can't try it.

Additionnal question; how long does it takes generally to be delivered?

Thanks a lot!
