I bought it for PDF reading and note taking.
I went for the iLiad (and not any other e-ink reader) because of its open-source software and the active developer community.
However, I recently switched to pocket-book 903, after my iLiad died with "frozen" vertical lines in its display. I got the 903 for the same reasons I bought the iLiad: Wacom touchscreen, good PDF support note taking. Unfortunately the PB 903, while generally bigger and more feature rich, isn't (yet) as good as the iLiad
