It’s not far-fetched, infinite growth and all.

Since Kobo e-readers have public library integration where I live and I no longer have an Amazon account, the Kindle I bought is just sitting there. If it pans out into a subscription model and Amazon also cans other forms of side-loading, honestly Kobo + physical books would be my only go-tos: why pay extra to borrow from Amazon when my taxes already go to a library system from which I can also borrow books? I’ve transferred the books I had on the Kindle. Maybe it can be reused with a pi should it come to.
