This all took at most 5 minutes from install to completed book download.
There were a couple of apparent glitches. The Kobo app said there had been an error and to restart the app.....but the book download appeared to be proceeding normally, so I let it finish and then opened the book to read it. So I'm not sure what the error message was for.
The table of contents in the book appears to not work....or I don't yet understand how it shuold work. If I touch a link for a location i the book, it presents a blank, white page....but I am able to happily scroll though the book directly. Fonts can be changed to serif, sand serif and monotype. A range of font sizes is available.
The default is very readable.
I'm sure any little glitches seen in v1.0.0 will be sorted out....and as it is right now, the app works.
I can install it, create an account, buy a book and read the book.
