Just for curiosity, I fished out my old Kobo touch, I had factory re-set it and wanted to re-familiarize myself with how it works. I then had an instant recall. To set it up you have to download the Kobo "desktop" app on your computer. I don't have Windows or Mac (I'm a Linux user) and I don't like wine much. Does Kobo still do that? One would think that with Android, a person could also download the app on their device and set up that way. Granted, this Kobo is as old as the hills, so I don't know if modern devices still make you do that ceremonial ritual
With a Kindle, all I need to do is log-in to my already existing Amazon account, and I'm done. I don't have to do a big song and dance. Every day I find reasons why I probably will never go back to Kobo.
