Me too. I also like the idea of being able to quickly open a text and read it anywhere, day or night.I've been sold on LCD readers for years for the simple fact that they allow me to read in the dark. i.e. I can be physically close to my wife and/or son without disturbing their sleep with my reading.
I'm teaching a classical literature course this semester, and we're currently reading the Odyssey (in a sometimes difficult 1891 translation). A question arose in class over the meaning of a particular passage, and it took me literally about two minutes, with an iPod touch, to open the Stanza app, search the Project Gutenberg database, download a different (free) translation of the Odyssey, locate the passage in question, and read it aloud to the class for comparison with the printed text.
This was using an iPod touch, with all its limitations of size and usability (though with the advantage that I just happened to have it in my shirt pocket). This kind of thing should be faster, easier and much more readable -- especially for a hurried teacher with clumsy fingers -- on an iPad. There are, for instance, web-based versions of the text including the highly regarded Samuel Butler translation -- but these are really too much hassle to deal with on a tiny iPod screen.
Sorry for all the annoying detail. But it will be specific uses and specific situations that determine whether people find this to be a useful, or even invaluable, device.
