If you're having trouble keeping up with the latest technology, well, you're not alone. In fact, you're probably part of the world's fastest growing demographic, the older IT user.

A new book that looks at how design is being shaped by these issues is being launched this Friday as part of the State of Design event currently on in Melbourne.
