An ebook has no weight. You can take it anywhere in a flash drive, so you can, for example, read it during lunch at work.
And how exactly do you read an ebook using *just* a flash drive? Ebooks are *less* portable because they tie you to either a desktop computer, which isn't portable at all, or a laptop, which is generally a lot heavier and more awkward than a book.
