Hi PortiaDaCosta
Since you're a new owner of the Sony I thought I'd offer a little warning of something I found out the hard way. E-Ink screens are very fragile. They have a thin glass layer which does not resist twisting or pressure so do not put anything on top of the screen, especially something that may exert point pressure.
And definitely do not kneel on it as I did. The results are not pleasing.
I'll be getting a hard sided case to carry it round in when I get it back from Sony.
