Using my Sony eReader, I found it easy to keep track of all the players while reading the book (and there are QUITE A FEW, but not as many as in the Red Mars series) using the notes function. I mention this because I’ve read a couple of folks saying they’re unsure of what the notes could be used for. Here’s an example screen shot on the right.
I can highlight names and phrases throughout the book, and the on-screen keyboard makes it easy to add my own thoughts to remind myself who the players are while reading. It's easy to tap the screen and switch between the notes and the reading. The notes stay with the book and get uploaded to the PC’s Sony software when I sync. Good stuff!
This picture also gives you a good indication of the "glare" that people have mentioned. It's more of an unfocused fuzzy soft reflection than a glare. You should see the glare/ reflection from my HTC Fuze cellphone as well as the HP Pavilion Entertainment PC in the den -- talk about having a mirror available all the time!!
UPDATE: Oh, look, I'm famous: I'm published on one of my favorite blogs!
