Not only that. To the GP: I read also on my phone (Nexus one) but I feel the backlight is not very gentle for my eyes, even when using FBreader in night mode. Also, characters are too small. To me, a (real B&W e-ink) Kindle is better, or a paper book.
Actually, if you get a phone with the AMOLED screens, you can read in direct sunlight. I have a Nexus S, and I do that every single day. I take it out of my pocket the moment I step outside, the screen automatically jumps to full brightness, and I have no problems at all using the phone to read emails, set up GPS while I'm walking to my car, or compose text messages. I can even do this with my sunglasses on.
