I most probably will buy a Glo this month.
Where I live there's no real competition for the Glo. I exclude Kindle on principle and the Nook Glowlight is much more expensive and lacks certain features.
I might have waited if Sony had announced a more up to date reader, but they have forsaken me.
I am still in doubt. I hope the Glo will not disappoint. I am still worried about the dictionaries. The fact that the Kobo representative on this forum ignored all questions about the dictionaries did not at all feel reassuring.
I know Pocketbook is working on a glowlight version too. I saw a prototype. I know they have more open dictionary options, so I might wait for their model.
