Just that really. I have a KOBO e-reader and chose a KOBO over a kindle simply because I would have the opportunity to borrow books from the library's digital collection. I don't understand why more people don't borrow e-books? My library has a fantastic selection of resources and often get new books digitally as soon as they're realised.
I save an absolute fortune not buying books unless it is something I really really want. Is it just because people can't see beyond buying a Kindle or think that other e-readers are rubbish? Or is it that I'm extremely lucky with my library's system / investment.
