Howard,
The speech is very clear. Very easy to understand. The only quirk I've noticed, is that there is no pause between chapters. Which if you were reading you would know, by turning the page.
So far I'm very happy with my Kindle2. I can download books to my laptop, and than to the Kindle. Or directly to the Kindle. You can shop for books from the Kindle.
I store my books I've read on a SD card in my Laptop. And I can reread them as many time as I like.
I have AT&T cell service. And have been without service, but I have always had wispernet on my Kindle.
I do hand sewing and crocheting, and I'm able to do that and read at the same time. Which makes be feel like I've accomplished something. My Kindle2 works very well for me. And reading with the headset on, hubby can still watch TV.
I've taken it walking, biking, and to the pool. But the text to speech draws more battery, so I have to plug it into the wall every couple of days. But one can also read while it's plugged in.
The text to speech was an important feature for me, and I'm very happy with it.
