i wondering what some of y'all do with the books you purchase to read on the ipad? whether it's with ibooks, nook, kindle, whatever. since i have a habit of not re-reading a book twice, i never buy a book unless there's a good chance i'll go back to it and those are usually some sort of non-fiction book. but there are a few books that are good taht i would rather read on my ipad instead of borrowing from the library. the ipad means it's one less thing to carry. and i'm wondering what poeple do with the ebooks since ebooks can't be donated like hard copy books.
