I'll choose e-readers - no contest.

Whilst I too love the smell and feel of a book, we buy them for their content not their smell and feel. If the lack of 'paper smell' bothers you you can buy a 'book smell' perfume to spray on your e-reader.I'd much rather carry an e-reader than the complete Encyclopaedia Britannica. I think my library of 3,000+ paper books probably weighs about a ton. Most of them could fit on my Kindle Keyboard Putting another book on the bookshelf may satisfy some people but I have trouble finding a space for an extra book on my shelves. I've used up all the normal space (two books deep) and have run out of space between the book tops and the next shelf! I like to read relaxing in a bath. I may fall asleep and a soggy book is not easy to salvage. Your e-reader may not like water either but you can read it inside a ziplock plastic bag far easier than a paper copy! My e-readers play music and can read my book to me. The only paper book I have that does that was bought years ago for my children. Can you get Internet on a paper book? Maybe this will be possible in the future when flexible screens become available. My Nexus 7 has full Internet, plays movies, makes video calls and with a small home made periscope takes pictures also. (OK - not very good ones)Price? In general e-books cost less than a new book. Second-hand paper books may cost even less but that may change.When you buy an e-book you buy a licence to read it. Most people are not keen on this but if you face a disaster which destroys your library - a fire,  your ebooks will still be there in the cloud whereas your paper books will be in the smoke. The 'wicked bible' error.Few books are perfect. They contain typos, spelling mistakes, grammar mistakes, timeline errors, sentences which could be phrased better. Once you've bought a paper book - you're stuck with the errors but ebooks can be updated. That's my choice. What about you?
