E-books - suggested answer	

1 	It's compact
Whether you're a student or someone who travels a lot, the e-book is a godsend. Either way, you probably need to take a stack of books, and this is a huge burden. Thanks to the e-book, you can not only save loads of space in your bag but also in your home. My shelves are full of books, and so are my office and basement. I usually have to give books away to make space for new ones. But no longer - with the e-book, the problem has been solved.

2 	It's always open
When I'm reading, I tend to get really absorbed. This means that I carry my book around the house, reading it while I eat breakfast, brush my teeth, chop vegetables, etc. The problem with a paper book is that I always have to find a way to keep it open and this usually means putting something heavy across it. Of course, this tends to obscure part of the page, which is a nuisance. With an e-book, it's always flat.

3 	It has an excellent catalogue
Almost any book you would ever want to read is already available on most e-books, and thousands more are being added on a regular basis.

4 	It's green
E-books are good for the planet. They help to save trees - none are used to make an e-book.

5 	It's the future
Sorry, but it is. E-books are what we'll be reading while we rocket to Mars in 2050 - either that, or our personal robots will be reading them to us.
