Check out the Viliv X70. It is an awesome device. To answer the question of why - I use mine for reading books, watching video, listening to music, taking notes in meetings, shopping lists at the store, mobile email, my cook book in the kitchen, GPS navigation both in my vehicle and walking. The list is almost endless. Have you ever tried to take a laptop out on a plane or a train. This is MUCH more manageable. Laptops are great because you can take them with you. This thing is better because you WILL take it with you.
