Thanks for sharing this info Jackie_w. Unfortunately, SQL table editing is rather beyond me, I can just about manage to follow instructions when other people have developed ways to tweak the device! I would love to try the Aura for a few days to see if I get on with it but am uncertain about the Kobo (or WH Smith) return policy. Maybe I'll wait and see what Sony has to offer later this year before making a decision - I wonder how strong minded I can be?
