I googled it and this
rave review makes it sound great! I wonder too, if the
Asus EEE 701 laptop would be suitable. It is very light and holdable -- much like a hardcover book.
Weight is an issue with these readers unless you want to prop it on a table. But then why not read on your PC?
I find that screen size is not so much the issue, but
font size is. A PDA screen can give you large text with a short line length. That is good for a fast reader. If I were wanting to view PDFs I would want a large screen. For fiction, it doesn't matter.
You can play with conversion methods on the Sony Reader to give you the font sizes you need. This is easy to do and the results are good. If your eyes feel better with backlighting, you might borrow someone's
Palm to see if that is a suitable solution and if you can get the font sizes you need. For a mid-sized screen the
eBookwise-1150 is cheap and good.
If you can't get a comfortable read otherwise and decide to drop > $2000 on a tablet PC, I am sure you will have a great time with it. The Fujitsu sounds like a supurb machine.
