Cons
Con All eBooks are in a proprietary format
Unlike other eBook stores, Amazon does not offer .epub's (a free and open eBook standard) for their Kindle devices. What they do offer is a proprietary format that only will work on their own Kindle devices. Sadly this creates user lock in as there is no way to take those digital titles to another reader without stripping the DRM from them (something that may or may not be illegal in certain countries) and converting to a format that does work on said other devices.
Con Amazon is an evil corporation
Con Bad communication
Con A lot of books are copy and paste from the web
Large selection, but there is an ever increasing numbers of books that are less than 100 pages, mainly created copying and pasting freely available information from the web. Searching for what you want is becoming difficult, with results showing lots of pointless and poorly written small books.
Con Not all eBooks sold on the site are Adobe Digital Editions compatible (.epub)
For some reason not all the eBooks available on the Kobo eBook site are downloadable as .ascm files. Most likely Kobo leaves this up to the publisher, as Houghton Mifflin Harcourt does not have a single book on the Kobo store that offers a separate .ascm download. What most users are unaware of is that the Kobo store is not primarily an .epub bookstore. Kobo uses a proprietary format called .kepub that only works on their own Kobo branded devices. Many of the books they sell do offer a separate .ascm file download, but not all. What exacerbates this issue is that there is currently no way for a user to know if an .ascm will be offered until after purchase.
Con Kobo randomly changes prices
Depending on whether a user is logged in, different prices will be shown on non agency eBooks. Non agency eBooks allow for Kobo to set the price of the title instead of the publisher and sadly it does appear as though Kobo has taken advantage of this to entice new users into thinking their books are priced lower than they actually are.
