From what Others are saying you won't be able to access the entire Android APP Market. This will be more like the Fire where Kobo is controlling the ecosystem. So unless you want to root it and load a custom ROM on it you are going to be limited by what Kobo will allow you to do. My guess is you are not going to be able to install the Kindle App in the stock form.
Read some of the comments here to see what they are saying about the App Store.
