for e-book:

1) you can have a lot of books in one e-book, not only one.

2) it's comfortable to travel with e-book, becouse it's weigth is very little

3) it is useful to have books in electronic view - you can't lost it or smth like that.

for traditional book:

1) traditional book damage yout sight less than e-book

2) it can't be broken

3) you can enjoy reading traditional book in original version - it's more interesting
