I agree about Marvin.
I read wherever I am... waiting in an office, waiting in line for something, lunch, dinner, I've even been known to read during the advertisements if I'm watching TV, and er.... the bathroom, too.
I'm thinking that Gerty might have things that I don't need/use. Don't think I would need a journal while reading a book, I don't know about the need of maps when reading a book... shrug. I've tried scrolling and my eyes didn't like it.
Marvin definitely works well for me. I just don't want to have support decreased or stopped.
