My hubby has hundreds of books on his iPhone. Loves it. It's always in his pocket anyway, for those waits at the doctor's office or in long lines. He reads it in bed to not have the lamp on. When he's traveling, all the books he's reading simultaneously are always with him, as well as hundreds of extras to start when he's in the mood. It's small and lightweight, back lit, adjustable fonts, etc. And, it's his iPhone, so he has internet, all his online newspapers, Navigon, TV schedules (can tell us where to find a Law & Order rerun), contact lists, cell phone, everything he could want. Now that he has some arthritis problems, he'll use it for EVERYTHING instead of walking up the steep stairway (former attic) to our son's old room where he has his desktop computer. He sits in the living room with his iPhone reading.
