Same here. B&N is "my" bookstore but I only buy eBooks to read on the plane. Lending and borrowing books is nice way of connecting with friends. You can technically loan (some) ebooks in the Nook ecosystem - but only for 2 weeks and you have to add them to your "group" or something.
The shackles that digital purchases bind you with make me resist buying digital whenever possible. Subscription services, like Netflix, are a whole different, and interesting, beast.
