Thanks for the kind word on my web page. I will try to update it as I find more info and do more surgery on my ST3500.

I had a look at the book you linked to. If I rotate the image and display it in full screen mode the text comes out pretty small, especially the captions on the pictures and illustrations. It is just fine when viewed in landscape mode, but then you have to scroll each page because it only displays about 1/2 of a page at a time. Scrolling isn't bad, and carrying a 3 lb computer is much better than carrying an 8 lb book.

Most ST3500s have an 800x600 display, though there was an option for a 1024x768 display. You can see what the book will look like if you set your display to 800x600 and open the book file. I don't have any problems with eye strain reading books on the ST3500. If you spend a couple hours per day in front of a computer you probably won't be bothered either.

Keep in mind that under best case usage the battery life will be limited to about 3 hours max. Since I have old, used batteries I am getting no more than about 2 hours use before recharging. I don't think it would be practical to try to use an ST3500 to replace all one's text books unless you have only and hour or two of classes per day.
