Reading by backlight
I'm so comfortable reading eBooks on my iPod Touch, that I don't feel the need for a dedicated eReader. A Kindle or other might be useful if I start subscribing to magazines, but I find the 3 inch touch screen, using either the Stanza or Kindle apps perfect for reading short stories and novels. I hold it one-handed, braced by my index finger and pinkie, using my thumb to page through.
My eyes really bounce around the page when I read. I've always had trouble focusing and scanning steadily, both of which are key to reading comprehension and speed. I find I read much longer and with much more enjoyment in my device than I've ever read before. It's like discovering reading all over again. I haven't loved books this much since grammar school, and I've always loved books more than than just about anything.
