Price
You can get very very cheap device that can read mobi, epub, azw (you name it) e-book. I myself bought my for 29 £ (if you wanna know what you'll get for lest than 30 quids click here -> Nook simple touch review). Although Nook Simple Touch is probably one of the cheapest, there are others with similar price range.Space
If you're living in share house, or some place not that much generous with space you'll love e-book readers. I'm myself not a big reader (irony huh?:D), but still there are few books I love to read when I feel like it. If I had to have them physically all the time, I can just stop here. Most of you probably use airplane as a form of transportation and unless you own King Air, there is limit how much your luggage can weight. Fighting for every damn hundred grams you can afford taking your precious reading material with you.Reading
Can you adjust font in your paper book? Unless you have magnifying glass you can't. Same goes for font, space lining - you name it. Flipping pages? Even easier just a click away.Dictionary
From time to time (specially when reading Murakami books) there is a word I don't know. So what do I have to do? Extremely simple. Hold my finger on the word, and dictionary will pop up description what does that mean. I wouldn't bother at all doing the same thing with paper dictionary.Books you're not paying
Popular books will be always available somewhere. You can download them really easily. OK, some of you might say - it's different format etc. Yeah, that's true, but there are free convertors doing much better job than official tools (oh irony strikes again big corps :D)If that is the case, you need convert something, here is the link - Ebook online convert (epub,mobi, azw, pdb etc.)
Sometimes, you can't even get physical copy even if you're willing to pay some cash.
It's not that I have paper books, but I just can't see the point buying one - especially when your budget is tight. If you don't agree, you have something to say comments bellow are always welcome.
There might be some grammar (definitely there are) mistakes. Well, I have done what I could :D.
