The Book has a basic web browser. I use it to download books from my local library. The library uses the Adobe DRM system as does The Book.
You can create an account on an ebook site like Kobo and puchase books in the Adobe DRM format using The Book's web browser..
I have done both while travelling, but I prefer to use my computer and the
Calibre library manager.
