I have owned Kobo ebook readers and found that there is little difference in those and any other Android reader. I now purchase only Android ebook readers and then put the FREE Kobo, Barnes and Noble and Kindle apps on it, as well as the epub reader that comes with the Android device. The most popular format for ereading is the Epub format which you can just about get any electronic book in. If I find a book on line that I wish to read that is any other format, I convert it to epub before reading or read it in the Kindle reader. Almost any book you wish to read, you can get the epub version.
I too am thinking of severing my use of Amazon. I no longer use Google either, using several other browsers instead.
But, if you are thinking of puchasing a Kobo ebook reader, you might consider getting a generic ebook reader and just installing the free Kobo app or one of the many other free reading apps available for download and install.
