Thanks for that info! Note that as a newbie to ebooks and ebook readers (and I don't have or need even a cell phone), I don't know anything about "Adobe Reader Mobile", but if its name accurately describes what it does, that will be good as I use regular Adobe Reader on various computers. "Fit Width" will probably be what I'll use most often, and "The scrolling is not a smooth function like on a computer screen, but jumps a displayed portion worth at a time", I can live with a jump as long as I'm not denied any parts of a page. The width of the screen of the JBL seems to be about as wide as an average paperback book, too.
I think you've helped me decide on my project for my upcoming vacation -- track down a local seller of Jetbook Lite (or if I can't fine one before my vacation, I'll order it on line).
Thanks again! I'll keep watching for your tips and tricks
