I am in the tiny minority. I use my Kobo to read (99.9% fiction), and nothing else.
I bought my eReader as an alternative to paper books. I don't use my Kobo to browse the internet, nor look at the time, nor to play sudoku, nor to preview books, nor to share information with social media networks, nor as a notepad, nor as a dictionary.
I have tried some of these features out of curiosity (and to test functionality), but not because I intend to use them regularly. I just wanted to know what my device can do, in case someone asked.
