It was definitely the avoiding Amazon for me and then the bookstore revenue sharing that @MildBill mentioned. If you have a library near you that uses overdrive or Libby, the integration for borrowing ebooks is also very slick on kobo. It syncs really nicely for that purpose in a way that Kindle didn’t always. At least that’s been my experience. The build quality is nice, and they have a good blend of features between the low-end kindle and the mid-range kindle in their base model.
All in all I find it compelling.
