Thanks for this discussion -- I am about to buy an e-reader for Christmas for my son, who is mostly Japanese
and prefers reading in nihongo. I asked a J co-worker who bought a Kobo Touch a few months back whether he was happy with it--and he said that he wishes he had a Kindle now, as the number of books available is greater. But given that my son would probably want to read manga mostly, I will go with Kobo Glo for him. He can always convert them if he buys stuff from the Kindle store. domo domo!
