E-reader newbie and very confused
I recently got back into reading but I don't have the space for physical, so i wanted to get an e-reader. But, one I have no idea which one to get and two I've been trying to figure it out by reading some of the posts on here, but got super confused about all the jargon and programs like sideloading, calbire, boox?
I kinda thought you just buy the reader and then you'd pay like a subscription for access to a library or pay for the e-copy of a book. It's very confusing to me and I'm sure plenty of questions like these have asked before and I just can't find them, but any help would be appreciated.
Also, I'm just looking to read books. No manga or comics, so any recommendations are welcomed.
