That's easy -- it's part of the Zoomer package. Normally I would read a
book; however, often I can't or don't want to carry a book along when I
carry my Zoomer. Therefore having a few games, my todo list, the ability
to take notes or write (I've done first drafts of short stories on my
Zoomer) and have some reading material, all in one compact package, is
a major convenience.
Also, I find that the novels I can get for my Zoomer (public domain,
therefore "classics" for the most part) I wouldn't read in book form. I'm a
constant reader, with a reading list a mile or more long, and classics
aren't high on my list. So when I have to read something on the Zoomer, I
have to read a classic, and I'm better for it. Just like taking two
semesters of Shakespeare in college - it was the only way I was going
to read the Bard. I enjoyed both classes immensely, but I still can't sit
down and just read Shakespeare.
